Best synth (I tried the others, they compete for 2nd). This app is exactly what it says, and then some. It offers a pretty nice set of effects on top of the oscillators and sequencer. It’s also very user friendly. It took me all of 20 minutes to figure out how everything worked, and I am a complete novice at producing. If you are looking for a portable synth to make some sounds on the go, you just found the best one. I searched through the App Store and tried others; Synth One offers so many more options, including saving your work to presets and exporting! Suggestion to the developers: just a thought for future expansion of the app, can we get additional base waveforms to work with? Triangle, sawtooth, square, and a low duty cycle square are nice, but the addition of sine waves and other, more complex wave forms would offer some nice new possibilities. Also, being able to add extra filters (that is, have 2, 3, or more filters at once) would be a very nice feature for the future. Lastly, having more than 2 oscillators would be great. There’s a lot you can do with 2, but three brings in a whole new dimension to things.

Incredible. [Update 2] please please please if possible, change the app into an Audio Unit. Interapp audio is so buggy - audio connection from Synth one to the DAW is constantly becoming lost. Happens with every iOS DAW I've tried - Cubasis, Music Studio, and others. And it's not just Synth One - other sound modules have the same problem. I end up having to either restart the module or the DAW to re-establish the connection. But I never have this problem with Audio Unit apps (plus the in-app integration, altering the module to become accessible inside the DAW, is very cool!). [Update] YES!!! Either I missed it before, or you guys added the arpeggiator tempo adjustment! Thank you!!! This synth is the best! [End update] Just get it! One of, if not the best synth on iOS! Awesome sounds, huge level of control and flexibility, and great support from the team. One thing - PLEASE add the ability to set the tempo of the sequencer/arpeggiator, not just the division length (and by the way, the label for division is misspelled as "dev"). That way we can record sequences that match whatever tempo we're using in other DAWs.

Can’t believe this is real, and even more shocked that it’s free. I’m a lifelong musician but have never learned how to do anything with a synth, so of course I’m still trying to learn how to fully use this software, but I am absolutely blown away that this is free of charge. I mean really, this may well be the most impressive music app I’ve ever seen, and for it to be free is unbelievable. If AudioKit charged $50 for this, it’d still be worth that and then some, but even if you’re not a musician you owe it to yourself to download this just to see the potential of music through an iPad these days.

Very Good for Beginners and Professionals Alike if You’re looking for Some Practice. I feel that this synth would be a very good start for music producers just getting into sound design or would like to know where to start when it comes to sound design on their journey. It’s very easy to understand and the guide will give some helpful tips when using the app and when applying that knowledge to other areas of sound designing. I would recommend this to any producer who would like to know where’s the best place to start when it comes to sound design since like other users said it’s very user friendly 🙂

Very high quality sound, free, open source, inspirational story!. First of all you have to give it up for the team that put this together. If you don’t know the story do some research! As for how the synth sounds? Well it has a very nice full sound and out off all probably 30 or so synths I have on my iPad, it manages to stand out with its own excellent characteristics. It’s free what are you waiting for, download it! And don’t forget to review it for them! If there are bugs that you find, please email support to help them, you, me, and everyone.

What an amazing gift this is. We were looking for a cool iOS synth to give to our child to help him broaden his interest and explore his talent in music, and along came AudioKit Synth One. It’s free, open-source, and truly an amazing gift from this team of talented individuals to musicians everywhere. Best of all, because it is open-source, it will only get better. Our joy comes from knowing he’ll be able to create music right away, and that greater details and capabilities of the App lie just under the surface, waiting for him to explore and utilize them. Many warm thanks to the Developers. We are grateful for your selfless gift.

Wow. This is a crazy good app The only 2 flaw I can see is that it’s a little hard for beginners to learn as there is so much to learn If you search up how to use it there is a free online book which is very useful but even that can be hard to understand sometimes And on a iPhone the knobs can be hard to turn and control. (If they made them like sliders that popped up whenever you held the knobs it would help a lot) But besides these things, if you know what you are doing I see no other reason to complain

Fantastic. I’m fairly new to iOS but have been using an EWIusb for several years with pc. When I switched to iOS I expected to and was willing to pay a lot for a good synth. Well to my surprise the best on in my opinion is free. The things that I like about AuioKit synth one are it’s layout is easy to understand, it’s intuitive and I was quickly able to adapt it to my needs. The thing that I won’t say don’t like as much as don’t understand fully is how the LFO works because I’m used to a certain type of matrix. With all the available presets I found ones that come closest to the sound I require and the ability to have a user bank and favs was really the seal on the deal. It works flawlessly with my EWI and my BlueBoard. I think I love this synth😏

Life after Synth one.. This app is a must have. I have forwarded this app to all my musician friends. And Ive been teaching non musicians to make music and therefore become musicians. I actually use this app every day. I’m exporting audio on the regular and using it with all my other music making endeavors. That includes using the iPad as an caustic style instrument. I use it at a synth module in my studio And i often import files I made on the subway to protools and everything between in the iOS world. Is there anything else.. well yah its actually endless. But I’ll stop now because I need to open my AKS1 and put up a drone tuned to my Ora and meditate. Peace!

Absolutely fantastic!. I’m an enthusiastic user of hardware synths in a keyboard-based studio. Pair this thing up with a midi controller and it holds its own to my Kronos, Motif, Montage, etc. in the synth department. Loads of patches that inspire on their own, and infinitely and easily programmable on my iPad, I just love this thing. Do yourself a favor and spend the money for their latest release Digital D1. It supports this project, and it’s the perfect companion to Synth One. To the developers: A heartfelt thank you for this iOS synth that is such a powerful tool to add to my portable studio. This thing is for real. This is the most exciting thing I’ve added to my rig in a long time. Keep up the good work!

Amazing Virtual Synth that competes even with many hardware synths and surpasses.. So I’m an audiophile, I love guitars, basses, drums, but my first and greatest love will always be programming and audio synthesis and it’s modulation. I’ve owned many hardware synths over the years, just to mention a few: KORG microKORG, M-Audio Venom, IK Multimedia Analog iOS Synth, and I still own my Novation MiniNova. Just tinkering around with AudioKit’s synth, quickly you begin to realize they meant business. It’s absolutely amazing the quality of the audio and the various components known to synths. Using a midi controller you’d basically be indistinguishable from a high dollar hardware synthesizer. Since downloading this free app, I’ve since purchased ALL of audiokits other offerings (some of which are limited - Bass808 being one of the nastiest Bass Synth plugins I’ve ever heard) and they are also great with support and service. 5 stars for the app and the developers. P.s. Any progress towards making this synth available with Garageband as an in app synth as opposed to inter-app audio?

“Midi Learn” is incredible. So many great things about this synth. Gotta shout out the Midi Learn feature. As a midi and soft synth noob, i was able to hook up my irig keys pro2 and start twisting the knobs and assigning them right out of the box. So many great presets that already sound great. Love the basic waves you can start with as well. Im building patches and learning. So much fun. Only criticism is that the sound drives my iPhone so hard that the processor cant cope and I get major crackling when I push a patch hard. Could just be time to upgrade my phone though. Cant hate the app for being so powerful. Thank You!!!!!

Better than every other synth app. This synth is better than any of the pay apps I have tried. Aside from the excellent interface the sonic sound quality is better and more alive sounding than most of my virtual synths. The range of the analog development makes it feel like you are working on an old Roland 700 or ESM Systems. The output is clean “fat” without getting muddy or stuttering from latency. The clock speed is solid. I found it works best with a controller that has lots of buttons, slides and knobs. I’m testing a composition using just this synth as my only sound source. My initial reaction is “wow, color me impressed,”

Best Free Online Synth. As someone who has wanted to get into music production even since I was a kid, I was never able to find the right apps to do so. I finally did some research and stumbled across this app - not only is it a completely free and completely functional, but it’s good for both beginners and pros alike. I’ve learned a lot about how synths work just by fooling around with the controls. It has a large bank of pre made patches that sound amazing. Another thing I love about it is the fact I can record audio from it through Garage Band. This allows much easier mixing and also means you can pair the app with the instruments on Garage Band. Get this app. You will not regret it.

Crashes with Audiobus 3. The app is great. I live all the sounds and customization I can do with Synth One. However, I can only link Synth One to Audiobus 3 as a audio source and not a midi source. When everI try and connect my keyboard as a midi controller to Audiobus 3 and then link it to Synth One, the app launches and then crashes and can not reconnect. I can only use Synth One in Audiobus 3 as an audio source. Then it works. This unfortunately won’t allow you to use midi splitter to split the keyboard with two different synth apps. This is a great negative for any live or recorded performance. All of Audio Kits synth apps like Digitalism 2000, work fine in Audiobus 3 when linked with a midi input. Just not Synth One. Audio Kit, please fix and I will give a 5 star rating.

Best way to get a kid started on synth music. Fora couple hundred bucks you can get a decent desktop midi controller and a camera adapter and have an incredibly simple, instantly playable pro grade rig that sounds like it cost thousands. Unfortunately it won’t work with a DAW if you have a PC without spending another $300 for a midi router. And at that point you might as well just save the hassle of outboard gear and buy a nice VST synth 😕. I’m constantly frustrated by the lack of Apple support for their audio/midi interface on PC.

Incredible for professional musicians & their babies. It’s a little hard to type right now because my son is so active in learning how to use the phone but I just wanted to say that this app is amazing and is really a fantastic tool for learning and also for creating. I haven’t really delved deeper into other features but from what I can see and what I have observed, it’s really something special. It’s probably one of the best musical apps, free or not, on the App Store.

Great for solidifying ideas on the fly. Everyone knows that a great song idea needs to be written down, or it’s gone forever. This has helped me create and fine tune my ideas. It’s especially helpful when I don’t have my DAW readily accessible. This synthesizer is top notch. Industry grade controls and sounds right on your phone. Thank you for this app and thank you for making it free. One ability I wish this app had would be a drum machine. Like a launchpad that took up your whole screen so you could play leads and basses within a scale without fat fingering the keyboard. That would be sick. Regardless, still a phenomenal app!

You only need this One Synth. I gotta hand it to the team involved in this synthesis project! The ability to record and export to wave is ideal when your DAW isn’t cooperating properly! At the moment I utilize the AudioKit Synth One on my IPad as my studio is currently mobile and not stationary. Loads of fun and the ET settings are far beyond my comprehension than what I have been doing. This Kit is definitely being added to my future live performance instrument setup! Thank You Much and Happy Holidays! SubCultural Consciousness Label

This is not great, this is extraordinary. I randomly downloaded this app. I’m a professional music composer and producer who’s been in the business for over three decades. I’ve owned most major hardware Synthesizers from Arp, Sequential, Moog, Korg, Roland, etc. I have most every software synth. The AudioKit Synth One is a masterpiece. It’s like rediscovering the joy of synthesis, of electronic music, and improvisation all over again. To be able to sit with my phone in my hand and a pair of headphones and endlessly switch programs and just play is such an extraordinary joy. This sounds, these programs, these combinations, these arpeggios are not consumer grade toys. These are professional, inspiring, ethereal level tools, an inspirational artist palette that trigger the imagination in ways that very few synthesizers do. I applaud you for bringing this extraordinary piece of technology into the universe, and putting it in everyone’s hands free of charge. Thank you thank you thank you.

A true gift of music to the world. Within the first ten to twenty minutes of playing with this incredible synth, I soon began to realize that I hadn’t even scratched the surface. I love the fact that I can see my wave forms in real time even as I began to manipulate frequency modulation. Not only is this a seriously powerful synth, its possibilities in my sound design projects have become even more exciting. To all of those incredible people from all over the world who came together to make this free synth a possibility, you have given a beautiful gift to the world

This app is AWSOME!!!. It wasn’t exactly what I was looking for, but I can’t believe how amazing it is! 😄And for free? Created by volunteers? That’s awesome you guys! If I could make a request it would be for better control of the hold note melody. Like if we could change the time signature so it will sound different? I love that I learn by just playing with the app! Hopefully the loops I’ve made transfer to Piapro studio, I’ll find out. I have similar functions in that studio but it’s hard to manipulate keys on a laptop. But this is fantastic, truly an asset! I still have a lot of exploring to do! I’ll write more reviews as time goes on. But this is truly a gem of an app! Thank you so very much for all of your hard work! I’ll be sure to recommend it to my friends! 😁 I can’t say it enough! This app is awesome and I really appreciate all of your hard work!

An excellent professional soft synth for FREE!?!?. Wow I can remember when I first discovered this synth but I have been playing around with it for a couple of years now off and on. I do not really know how to play keyboard or anything else for that matter but hey with this app you dont need to know anything just open it up and start exploring. And it works with Garageband too so it is very easy to record. The samples and sounds are amazing and all the user controls are mind boggling. I am still also studying with and app called synth tutorial which explains all the terminology and explains all the ways to use and change the signals and sound waves. I am 71 yo music hobbyist and I just love learning new things. So thank you to all the experts worldwide that have come together out of charity for us poor working class folks to put out a free professional music creation app like this. It is really fun and entertaining.

It has a poor palette of sounds. After playing on its own onscreen keyboard, I can say that the interface fails badly. The keys are either too small or too large, in the option of dark mode you can’t see the keyboard at all, the notes played cuts or don’t sound at times. Better make a onscreen keyboard like it is on Sunrizer synth or better yet on Bismarck bs16i. I think the synth engine is good for create new sounds. But the presets you included are pretty the same each other, slow and nothing to wow about. Maybe the arpeggiator has something good but I don’t use that in my music. I feel this synth was exclusively created toward some kind of music, maybe reggaetón or hip hop and may not work with all kinds of music. I play electronic rock but I prefer Poison-202 or Sunrizer on the iPad. I hope this sincere review will help you to excel your project

So MUCH FUN!!. This app is amazing! It’s so easy to use and so fun to play with every option that is available which there are tons it’s well worth the purchase.... ITS FREE! So why not try it you may just find a musician lives in you after all or maybe just a sound effects coordinator or just a helpful tool when your playing games at the wedding party or birthday party or whatever this truly is one of the most versitile apps out there and very worth it!!! Well done to the creators and the dreamers that are working to keep this app amazing thank you thank you!!

Very Impressive. A free wonderland in a box !. Truly Amazing for all the sound it can synthesize -.A great list of presets and that you can transform to something totally different -. Unlikely other Synth app the Sounds bank is not tacky and yet it's totally free, no need to buy preset package. Besides it come with a sequencer, and many tuning options , from normal to bizarrely interesting -. it's not difficult to lose track of time :))) I uae this app on my phone, if you tap on the microphone in sequence, it create a cool effect -

Awesome. I have to say, I have owned many hardware synths from Kronos to M1 to Motifs,Kurzweil. Ensoniqs(showing my age with that one lol). I open your app and am completely blown away with the level of depth and movement in some of your patches and tweak able options. I also on your paid app ,just another level together. Never thought years ago I could this quality of sound on an iPad or iPhone that sits in my lap. You guys truly love you work. I have never written a review but after reading your updates notes and listening, using your latest version...all I can say is AWESOME. Your other apps...what can I say, Just as good ...my only complaint is a persistent battery drain on my 2018 iPad Pro that would run in the background ...even if you had global background turned off. Had to go on global and specifically go into the background setting of fm player and turn it off. Trust nothing major. Have a DX on a tablet is; awesome. Can’t wait for full AU3 integration. Again keep it going and keep inspiring us to create music !

I don’t normally write reviews…. But this app is absolutely phenomenal. I made the decision for you, I downloaded all the other synth apps and this one is just the best option because it’s free. I can create endless amounts of custom sounds effortlessly and export them straight into dropbox as wav files. I can then use them as a sample in FL Studio and create “one shots” that I can then put into midi chords to create melodies from custom sounds. It’s just so much easier to do it from my phone. Thank you

Appreciate synths more!. I honestly never really worked with synth modules of any kind. I would use a preset to play along with a piano or Rhodes or something. When I heard about this app, I said “why not. It’s free.” I love it so far. I haven’t been able to use it live yet (I’m a musician), but man it makes experiment more than I ever did before. I’m more interested in the bass I can get out of this. Although there are presets that come with the app, I played around and ended up saving presets of my own! Once again, I have yet to use it live. I also haven’t tried a midi controller yet (my connection kit has been ordered; I have an iPad Air 2). Let's hope the 5 star railing stays lol

WOW!. I’m am blown away by the depth and versatility of this app, not to mention the ease of use, responsiveness and incredibly user friendly layout. I’m a very seasoned and experienced musician, my intention was to download this for my son to give him some synth tools without having to learn overly complex software. I’m pretty sure he will have fun with it, unfortunately for him I have not put it down long enough for him to use. Without getting to deep into the detail, I’ll just say, try it for yourself and see what I mean. Thank you to the team who developed and gave us this app, it’s simply outstanding.

Speechless. This is a masterpiece. I say “this”, because what do you label or call something that transcends an app, or software?. It’s more. I’m not saying it’s a sentient being here to change the face of musical mediums as we know it, im saying that once you’ve ran the gambit of apps and plug-ins and beat makers and midi mapping monstrosity’s this feels like a breath of air after holding it through what seems like an eternity of sub par Mickey Mouse music programs crop dustings! LoL I’ll stop, but for real, hats off to the developers, contributors, testers, and everyone who agrees.

Excellent Synth Suite. I wanted a synthesizer app to play with some original songs. Wasn’t looking for anything too complicated, just something to do a sequence or two on. I thought I’d check it out before I went to bed. Two hours later and I was still finding things to tweak and play with. There are an insane amount of options, so it’s really impressive how user-friendly the interface is. The fact that it’s open-source let’s you know that it was created for its functionality, not to turn a buck with an iffy app. I’d recommend it to anyone, and I recommended it to other musicians whenever music apps are brought up. Thank you for giving me a way to experiment/learn with a feature-heavy synthesizer without having to sacrifice a lot of money or space.

Can’t beat this FREE synth. I am a complete beginner with synths, so I use this app to play. The app is pre-loaded with a lot of presets, but you can also just start with a basic sine/square/saw/etc. if you want to get a little more custom with the sound design. Plus you can easily capture sounds by saving presets and making recordings with the press of a button. I love recording ambient jams and just having fun! Not sure yet how to integrate this with any kind of DAW or synth setup, but imo this is a powerful app.

I highly recommend this app to everyone.. I just watched the video for the starting of this app and it’s creators vision and I must say that we need more people like this in the world 🌎 I will never forget the message behind this app and it’s creator and everyone else who’s heart ♥️ is as big as His. Much love 💗 and many blessings to everyone who contributed and contributes in the future and I highly recommend everyone to watch their video message and mission of creative ideas and sharing ideas and creative ideas for the future. Thank you 😊 I appreciate you sharing this wonderful Synth with us all.☮️💜😃🙏⭐️🙏♾🧘‍♀️🧘‍♂️🕉⚛️

Fantastic. I’ve always loved instruments. I especially love the synthesizer. This is not just an app. It’s a full blown synthesizer. Might be on an IPad, but hook it up to a keyboard and an amp and you have a synthesizer. Totally worth downloading. If I could give it a 10 I would. Thank to you guys who came together and made a true masterpiece of an app. And hey you don’t buy anything, or have to watch videos. I mean everything about this app is beautifully and perfectly done. Don’t have the money for for a synthesizer, well here you go. Thanks CDM

Incredible!! One of the best synth apps for iOS to date!. Amazing app! Extraordinarily easy to use, fantastic sounding patches, and free! When I first downloaded the app and was asked for my email address to unlock additional patches, I used the address for my throwaway account. Once I started using the app, I was so impressed with the ease-of-use and quality of patches, that I deleted the app and re-downloaded it just so I could use my primary email address for notification of any application updates. I’ve downloaded most of the mid- to high-end synth apps for iOS (free and paid) over the years and this one easily rates within my top five overall and is my current favorite. Each time I launch this app, I experiment with new patches and I’m still awestruck with how amazing they all sound. The only thing that I would ask of the developers is please, Please, PLEASE port this to macOS and consider making a pro version for both platforms. I would buy them without hesitation!

One of the best. This synth has a very large range of sounds and it can go from dirty to clean, atmospheric to percussive. The feature set reminds me of the expensive Korg apps. It has a great sounding engine and the fx are all usable. The reverb isnt too metallic like many others imo. The two kaoss style pads are an awesome extra for a free app, or ANY app for that matter. The filter is warm and smooth, LFOs can go from slow to crazy. Envelopes are also mainly very smooth even with fast attack and long decay, etc, no click but good punch for drums. The arp and sequencer are the kicker, just so good and very intuitive, wish every synth had a similar feature. I cant say enough, this is a “go to” for so many uses I couldnt live without it. If you like this app try D1 and FM Player by the same dev. Only con is the obvious, AUv3. The documentation could be a bit deeper but I feel that way about most apps and this one is actually pretty good.

Delightful DAW Delivers!. Thank you to all the designers who took time to make this happen. I have been so happy with its responsiveness to input using my keyboard. Haven’t tapped into the midi capabilities yet, but all things considered, there is so much creative potential here, it’s a power trip. For anyone trying out a synth app for the first time or if you just need to test your keyboard’s functions out, this is a mainstay for your phone and tablet to maximize their sound-generating capabilities. If I had a personal desire to improve the app it would be to allow it to continue playing in the background so I could use other apps simultaneously. Otherwise it does everything you need to get working on your own synth sounds and sequences.

I Am Addicted ;w;. So I was just listening to Neil Cicierega’s Spirit Phone commentary video and I heard him say Synth One and I was like, “Okay, it might cost something…” but just then he said it was free and I HAD to try it (thanks Neil!!) I do not at all whatsoever regret my decision!! I love playing around with it! I have never in my life used an app with synth noises let alone make my own! I have it on both my tablet and phone so I can pretty much use it anywhere. If you’re looking at this 10/10 recommend!

Amazing app for samples. This app is amazing for producers who need new samples on their beats. I would highly recommend it. The save import into any DAW easily and is easy to use. You can also customize many of the standard sounds that you get on this app and adjust there length in reverb, pitch, echo and so many more things. there are hundreds of free samples that are on this app and it makes creativity endless. From any genre like EDM to Rap, you can find something that will definitely fit your style. Go check this app out I highly recommend it. From, Lil Nucleus

Solid In Every Place. Words can’t describe how impressed I am by this app, there’s so many great benefits about it, it’s free, no in app purchases, hundreds of synths by the community, amazing settings, and great sound, how can you not like this app? My ONLY concern is that I’m unfortunately not able to use it as its own keyboard on the GarageBand iOS app like some other app such as Sensual Sax for example. If I were able to do that, that would check off everything off of my list for this app and make life a whole lot easier.

Fantastic app. Having no background in audio engineering or synthesis, I feel able to play with just a small subset of tools the pros use. This is a great app for exploring different waveforms, sounds, and just fiddling for awhile. There are a couple bugs (mostly spotted on the iPhone) - Switching filters stopped working when HOLD is applied on the main board. Playback is muted until the app is closed and reopened. - the app crashes when oscillators 1 or 2 are frequently adjusted while the arpeggiator is on - The waveform adjustment buttons on the main board have misshappen touch areas on the iPhone. Maybe i havent learned how to use them, but: - The Glide dial doesnt appear to have any effect. - The Legato button doesnt appear to have any effect. Feature requests: - The ability to record a single midi track to disk (for those of us without an external source to do so) - See the audible reproduction minimum and maxiumum lines (in Hz and kHz) on the waveform display by device

Very good. This is a very good synthesizer. However, when I use it as an instrument in GarageBand, I have to switch back and forth between the two, which annoys me when making a song or beat over 90 BPM. I just wish that there was a way to directly load it into GarageBand like for say, Synth Master Player, which has a extension instead of just outputting the audio into a track. What I’m trying to say is instead of using inter-app audio just use Audio unit extension. Other than that, this is a great tool for musicians, especially beginners to make their own patches or sounds to use in production. Thanks to everyone who took their dear time to make an amazing product. Have been using this for over a year now and still loving it.

It’s rated so highly for a reason. There isn’t much that I can say about this incredible app that hasn’t already been said (more eloquently as well) by other reviewers, so I’ll keep it brief. Synth One is an absolute *must have* for anyone who is even toying around with the idea of making music on your iPad or iPhone. Seriously, you can’t find this kind of well-designed UI, incredible presets and precision control in apps that charge $20, 30+ or even a monthly subscription fee. The fact that this app is FREE and OPEN SOURCE is incredible, and it is one of my go-to examples that I use whenever I am mentioning to someone about how the best products, services, applications etc. in the open source world are those which are built by people who truly love what they are creating. The people who worked to bring us this amazing app are genuine lovers of music and you can tell how much effort and intent went into every part of the end product from the moment you fire it up on your device. Don’t hesitate to download this, just do it.

Please add DOTTED-8th-NOTE to Delay's Tempo Sync. This thing is almost there... So good and so fun! The one missing "feature of a feature" that I feel is quite common, even on stomp-box delays and in various music apps is a setting for a dotted eighth note delay time (an 8th plus a 16th note). This would allow much easier creation of rhythmic effects on a 16th-note pulse that are the backbone of tracks from Pink Floyd (ABITW Pt. 1 and lots more, on The Wall and after) to Kraftwerk & The Orb all the way up to Deadmau5, LCD Soundsystem and lots of modern trap, house, hip-hop, jungle, w. coast bass, techno, and other genres. Right now the app has all the triplets, which is cool, but not the same thing as the dotted effect. Synth One could consider adding it for 16th and/or 1/4 note intervals but they're less important. Your users will get a lot of mileage with just dotted-Eighth making a 16th-note rhythm unless they are tempo extremists. =) One can come close, setting delay time without using Tempo Sync, but the control is honestly jumpy and hard to finesse, and if you change the synth global tempo, it's wrong again. I humbly offer the last otherwise well-deserved star on this review in return. (It's open source; I suppose I should just learn how it all works and add it myself LOL.)

5stars it takes a huge good to git top. This app definitely deserves five stars one it really is free to it is what it says three well the controls the interface how smoothly it runs and it literally as I said does what it says I can plug it in is it is a medium but I can use it as a direct sound input I can use it all by itself. Oh guess what it’s free and that’s what it says whenever you ever got that app that is not full of junk and just tricks you to download it so you can pay for what it doesn’t do....??? Thank you AUDIOKIT and everyone who put it together... I have never or rarely give five stars because I’ve stars is the top you can get which means you are the best of the best what I have to say that through I search of sense media and put in any other way to help produce my mediocre talent have music this is definitely the way to go

Powerful, gorgeous sounding synth for a wonderful cause!. With the arrival of this synth app I feel as though iOS has finally reached a level where the instruments on my tablet are just as valid, powerful and great sounding as my actual hardware gear. Between the ODYSSEi, the Models D/15, Kauldron and now the AudioKit Synth One, it’s obvious that our phones and tablets are not to be taken lightly as an option for creative music endeavors. That’s not to even mention the midi capabilities, Ableton Link and other utilities that have been developed as this new frontier of electronic music continues to grow. Just think what machine learning will be able to contribute in the not-too-distant future! The fact that this was free is such a wonderful blessing for the world! I was confused after I opened the app and began to noodle with the synth engine - it sounded way too good and had too much processing functionality to be free! Then I watched the intro video... wow! As far as I’m concerned Matthew Fecher is the patron saint of public music education! Thank you so much to everyone who was/is/will be involved with this project! You’ve inspired me to learn coding and work on developing my own functions to enhance the Synth One!

Absolutely phenomenal. This synth sounds amazing, looks amazing, has more features than you would expect, and it’s free!! This quickly became a favorite synth of mine; I’m more pleased with it than apps I’ve paid $20+ for. I’m running it on an Air 1 and haven’t run into any performance problems with this. Some features I really dig are the oscilloscope, the tuning controls, and the effects. It’s cool being able to see your sounds in real-time and not many synths—hardware or software—have that feature. The tuning page is really inspiring because you can get some nice variations while using the sequencer. And the effects sound absolutely beautiful. I also enjoy the ability to scroll through the different pages while playing the onscreen keyboard. That’s not where the awesomeness of this app ends though. I cannot speak highly enough of what Matt and the rest of the team have pulled off here. To me, the greatness of a synthesizer is judged by how immersive the playing experience is, and Synth One delivers. You can quickly get lost in playing this because it is just that good. If you have an iPad, you need this app.

Love these apps!. All the apps by AudioKit are amazing! I just love the sounds they’ve recreated! They were alright in the beginning, but as they’ve developed and added new features and sounds, they’ve become indispensable in my music! I’d be glad to pay money for these apps, but it’s crazy how they’re free! I notice I’m using a lot of explanation marks lol but these apps are just so good! My only issue so far is that when I’m using it with GarageBand, it seems to forget that I have the apps installed on my iPad. I don’t know if it’s an issue with my budget iPad, or GarageBand, but it’s a little annoying. Other than that, these apps are incredible!

Feature request. Hats off to the dev and audio team behind this amazing app. This is truly a well put together app and I can tell a lot of thought was put into this. Also, thanks for making it free!! Now to my feature request. Obviously I could hook this up to a usb/midi keyboard, but what would be really cool for those times I’m on the go is if the keys would map to the Apple Smart Keyboard. That would be amazing. The touch screen works flawlessly, but for that added accuracy of having a button to press this would take the portability to the next level. That is all. Thanks for creating such an awesome app!

One of the best. There is a big crowd when it comes to synths, but this is a stand out. Being free in this day and age is astounding. Many thanks.

Incredible. Fantastic App! The variety of sounds it can produce is vast! The controls are intuitive and user friendly, and best of all, it’s free! Really appreciate the energy and effort it would have took to produce this app.

Great app. I just downloaded it and the more I make music the more I find new controls. I would like if it could have a timeline and loops but that isn’t for synthesisers so I don’t mind. Other than that, it’s an amazing app.

Love this app!. Really great app. Easy to use but powerful and sounds great. I know you’re all volunteers but it would be amazing if you could please add support for AUv3 to allow better interoperability with garage band. Thanks again!

So much in such a small package. Fantastic synth engine rivaling the big boys! Worth everyone’s time. Can’t recommend enough.

From David in Australia. You have to be nuts to pass this one up great job guys thanks for everything especially to Doug at the sound test room for giving a great demo on this if possible I would give 20 out of 10 it sounds great just on a Bluetooth speaker can’t wait to hook it up to my recording studio

Insanely good. That this is free blows my mind. Feature packed, amazing quality, loads of fun. Blows other free music apps out of the water by miles and miles. It’s beautiful that this exists. Thank you to the team behind this app.

Love this app. I like this synth a lot but can you add more sound come from 80’s time, thanks, 5 stars still

Cannot express enough how awesome. The most fun instrument I've ever played. This app is legit the main reason I bought an ipad, and I'm glad I did! Absolutely awesome for Improvising in.

Forget the rest. Just get this app, AudioKit Synth One is fantastic. Push the keys and create your masterpieces. These guys are the best for creating this open source app with lots of extra free downloads. Sounds amazing! Interface is stunning, I’m sold!

Immediate. Everything about this app is immediate. The layout gives immediate access to plainly labelled controls without distractions. The settings can be manipulated easily to produce an infinite variety of sounds. Despite the cliche, this may be the only synth you need.

Amazing. I downloaded this this morning and it’s already my favourite thing ever. Thank you! 🙏

Presets alone are awesome. Having a ball playing with this and I haven’t even progressed beyond exploring the presets.

Noob compatible. Incredible even for someone that can’t hold rhythm.

Awesome. This is a proper synth. Has more great stuff than most of the much more expensive apps. Very intuitively set out and easy to use. Excellent content. Highly recommended

Powerful soft synth. Wow! What a great app. All the power and possibly better functionality of more established and expensive pieces of software. I’m using the app just for idea generation, so haven’t added it to my music production workflow but it seems perfectly capable if you are an iOS producer. The list of patches and presets are the perfect launching pad for playing with ideas and the app offers all the options you’ll ever need to craft the sounds you’re after. Thank you for embarking on such an ambitious project and then to offer it to the world for free, they reserve a special place in heaven for people like you. Synth on, Synth One!

So Good.. Amazing attention to detail, killer sounds and free. 10/10 would recommend.

Synth one . Synthley perfect. Still speechless ! Really cool bit of gear ! And for free ? Open to improvements? I am impressed .

Great Synth. Great sound, heaps of presets, two oscillators, sequencer, effects, filters, two x/y pads, midi integration, auv3 coming and all for free..! This synth is also open source so you can add to it if you have the skills. What more could you possibly want?

Amazing app. I especially went and bought the Korg Microkey Air, (Bluetooth) keyboard to use with this app, and it runs so so well via Bluetooth, I just want to say thank you to the developers of this synth, the sound it provides is awesome I just love it, and all the presets are spot on, plus the app is totally free, I’m feeling the love with this, it’s all put together so well with love. Keep em coming guys, I will be happy to purchase anything you bring out synth wise in the future..five stars from me.👌👌👌

Awesome not so little synth.. Fantastic app. I’m using it when I feel to stressed with my work or on the plane on short flights.

Sdderccfgvccf. Canberra I have to be at work soon to be there soon to get back in the car if I can find something else for my truck and then I’ll really take it sir Orange soon to have the car ready soon soon to

Thank you. Simply amazing. This is a sonic beast. You all deserve the highest praise.

Unreal. Honestly this team are magicians and really nice people. They have given this app to us. It’s one of the best out there and unbelievable value.

Quality plus. Thank you for making this app. My projects are richer for this synth.

This is Better Than My Hardware Synth!. What an amazing app... I would pay for it! If i had the money for it... Please don’t charge for it although...👌 Has routing written in for a mod matrix understanding also. Too much to say...The makers have made a real service for us.

Flexible tool and great for learning synthesis. Using the downloaded booklet and working through examples teaches principles of synthesis. A great way of learning and increasing your sound options.

Absolutely must have. This is a fantastic free and open source app that will definitely not disappoint anyone. There is nothing much missing here. I am only a novice with synths but I am having a ball using my keyboard to record an mix tracks. Definitely one to get.

Amazing.. I am amazed that a synth on a phone can sound as phat as this. Awesome job!!

Fabulous free app. Thanks to all the devs for making this free app. I have it hooked up to an Akai MPK Midi controller and finding it a great entry level app to learn about synthesis.

Tremendous potential. Even a little tike can mess around with this one. Completely full and functional. But still a pro tool.

Wondrous App That Opens up Options. Recently through the magic of Bluetooth midi , have an MPC 61 key connected to this astounding app..I can layer the sound of the MPC with one of the great presets …especially useful when using the arp ones. Some of the presets on the synth one app , really blend in with the Akai MPC 61 presets . The audio out goes from an iPad 9 headphone jack back to the MPC input 1 . Using an audio track on the MPC , and a plug in track or drum track ect on the MPC enables one to record both presets( or more) ..without fussing with midi interfaces . The combination of sounds is astounding this app really presents mix ready tones . Have downloaded the synth tutorial book …wow …and this is all FREE? Bravo to the souls behind this app. I would give 6 stars if allowed.

Essential!. A free, fully featured iOS synth? Yes please. Huge respect to everyone involved in making this!

Awesome work.. Seriously cool synth with a fantastic approach. Five stars. Music is the best thing in the world and you guys and gals have added to the language. Peace. What a great piece of music software!

Unbelievable, incredible!. Surely this cannot be right, I mean there must be a catch? This is really free? It is incredible and amazing....hands down the most value for (no) money app you can download! I haven’t got an ounce of musical talent but the fun to be had with this - it can keep you entertained for hours. Thank you.

This app is just special. Such a wholesome and top quality app. This one's a must have!

Absolutely brilliant. This app mkes the hairs stand on the back of my neck.. Great interface, easy to grasp and tweak and sounds sublime. Do yourself a favour and get the free patches too! Very happy, thank you to all the developers for creating something so amazing.

Incredible!. An amazing sounding synth. Such a rich variety of useful patches. (And then I discovered I was only exploring one of lots of banks). Inspirational

Need help. Great app just a beginner how do you record music as seen on web

Most Useful. Can’t write much at the moment as I’m in the middle of a rad jam 🎵 This is a really good app. The global tuning feature is very handy for matching the tuning of acoustic instruments or other samples.

Best synth app by far.. It just works so well on my iPad. I use it all the time for recording. 👍🏽👍🏽🇦🇺 2 thumbs up!!!

Awesome sounds, and free. Brilliant project aiming at putting a pro level synth in anyone’s pocket. Great collaboration from the community. Buy some merch to support AudioKit.

Awesome and comprehensive. This is a gem. A truly integral app. with full and professional support from those who developed it. Deserves applause.

Best out there, including the expensive paid ones!. This is a no-brainer. This does what it says on the box and so much more. I’ve spent a stupid amount of money on iPad and iPhone synths from big name companies and this just wipes the floor with them. Check out these guy’s other apps too, they are ALL killer!

If it’s not part of your kit...why not?. I’ve been using SynthOne for a while now and it remains one or my go to apps. Over the years I included it in my live music as well as laying down tracks. I’m really looking forward to being able to run many instances of it at the same time in AudioBus 3 as an AU not just as an app.

The most Amazing sounding synth on the www. Simply put it sounds great and is relatively easy to use plus g it into GarageBand or the daw on your device and swoon .

Well done people, welll done what this does for the world is a beautiful thing!. I thank all involved in this endeavour, your all to be commended for your efforts. My sincerest thanks

Awesome goodness!. It’s free and the sounds are fantastic. This is becoming my go to app. Would be great to have tap tempo and external midi clock sync. But it’s free....already a big treat! To the people behind this creation thank you very much 👍.

Best music instrument app on the app store. This is a really good app that anyone who is in to music should try. I have never used an synthesiser before so all the settings and stuff were a bit overwhelming but it was to mess around with all the settings and try and find out what they do. 5 stars 🤩🤩🤩🤩🤩

Excellent Synth. Coming from an old analogue Mini Moog background of two oscillators & one modulator oscillator, it was easy to get your head around the main screen. It has a unique sound closer to the modern FM synth with its ARP emulation. Very happy with its fidelity, effects and loop functions.

Bucked.3333. This app is something else it is very educational to learn how to mix sounds thanks for the opportunity yes everybody would be like you guys everything with no smoothly again thanks I am learning

Excellent free synth app!. Thanks to the developers who put in the the time and effort to create this fine synthesizer app. Hours of fun for sound and noise geeks.

Synth. Génial

Amazing. Great interface and patches. Love how it directly records and exports even sessions across multiple patches. Makes it very easy to bring into other projects.

Just Sick. Incredible sounds. Only just exploring but amazing so far.

World Class Synth Top Job From Dev. The sounds on this amazing Labour of love SYnthy beast is simply, awesome. What lovely and rich sounds it makes. Nothing to risk here as it’s free and a world-class app. This true Labour of love to the iOS music world is a rare and precious gift so getting this amazing music app is a no brainer. Top job to the Dev~you have a fan for life. Congratulations on this historic release and for the monumental next leap for iOS synthesizers. You just set the bar that much higher. Thank you for this incredible gift to the world. Cheers!

The best tool I have ever used. The best app so far that I have on my iPad

Great synth. This app is so fun and well done

This app is great, it’s a lot more customizable to make music. I like to experiment with this app and see what I can come up with to make music, I struggled to make music in the past but now with this it’s a lot more easy once you get some basics, totally recommend

Doesn’t work on iPhone 12 mini. Well, sort of. The synth does work, but the left side of the main view is cut off, the bottom of settings are cut off, and none of that is accessible. Other than that, it works, and I love to play with it more as it seems quite good, but I can’t access all the controls.

love this app. I use it so often and have made countless tunes with it. Adore it! the rainbow option for the keys makes for a striking performance aesthetic too.

Simply awesome!. What, a free synth combined with a lot of features and Free? Simply awesome! Thank you so much!

Just the thing. For an old musician revisiting music in new & exciting ways. Helps me understand our eurorack.

blown away. I can’t believe how amazing this synth is. I had no idea what I wa a getting into when I downloaded it. It’s fun, easy to use, has amazing documentation for learning. It’s both a great to teach folks the basics of synthesis, but as a more advanced producer I also love it for fleshing out ideas and keeping my music brain active. It’s a little friend you can keep in your pocket! Runs great on both my iPhone XR and my iPad 5th gen.

EXCELLENT APP. This APP is AMAZING. You can literally get lost for hours in it. MANY THANKS.

Great synth!. Wonder and amazing. Absolutely invaluable to my creative work. A shout out of thanks to all who have contributed.

Merci. Fantastic les sonorités sont très riches et li me sont très pratique pour. Le projet sur lequel je travaille . Merci .

Gratitude. When I know why you created this app. You deserve more than 5 stars review. Thank you so much!!!

Great but…. I really love this app. There is a lot of quality here. But I have a problem using it via audiobus in fruit loops mobile. This is perhaps not even a problem with THIS synth, but a problem with Fruitloops mobile, I don’t know. But I’ve tried and tried to open it from within Fruitloops mobile, and I cannot for the life of me get it to work without distortion/crackling. I’m using an iPhone XR. If there’s a solution to this, I would be over the moon for this synth app. And regardless, I highly recommend downloading it to use, especially in standalone mode. Koodos to the great developer work on it. I really appreciate it.

Great!. This is Great for playing around or if your trying to get started playing,Great game love it!!!

Brilliant ‘warmth’ from a software synth!. Playing with synthesizers since the Fall of 1975, it be often easy for me to turn my head away from a lifeless digital patch. Right ‘out of the box’ though? Audiokit’s Synth One, should not be free! Early into it, the sound of this monster, from my i-Pad through my Sony MDR-7506’s? Whoa! This is a keeper, in my personal ‘studio’! Well phricken done peeps! Many thank yous and much respect! 🫡 Ryk Thekreator - the hexInverter.com Liquid HiHat innovenvator 🇨🇦

An App Synth for the future. There’s obviously been some great thought put into this app and it’s sonic capabilities.I’m just discovering how to incorporate it into my Bluetooth musical setup . There’s so many amazing sounds, can’t wait to see what’s next thanks so much to the developers it’s awesome. It’s definitely a wave of the future.

Great synth !!! Great to be able to create new voices. I have found this synth to be a lot of fun to build new sounds and to learn how synths work. Truly a great app!!

Asymetric and symetric sound. More than five octave filling the entire loading capacity that’s representing 88%of acousticien piano (symetric parabole ellipsoïdal conversions) . Asymetric keyboard conversion, both and third octaves reversed like à half and symetric 172 Touch tone dial . Thank’s for the opportunity.

Badaboom badabing. Honestly incredible for experimenting.

Hard to beat. Synth One is the best money can’t buy… And the best all questions marked. I like the simplicity of it as well as the fact it was designed by musicians from the get go! A wonder!

Wow. Powerful synth for free

Truly awesome. So many presets to experiment. Better than video games

Very cool. New with synths. Great for learning

🤯🤯🤯🤯🤯. 🤯🤯🤯🤯🤯/😲😲😲😲😲

False mod wheel destinations. Contrary to what is stated in page 65 of the manual, mod wheel effects LFO “rate” rather than “amount” (aka depth). This is a problem for me when trying to design sounds that use the mod wheel for vibrato. Once this is fixed, I’ll have no problem giving it five stars.

Excellent. Best free app I’ve ever used!

Amazing. Hundreds of free sounds. Got this for live music in basement. Always wanted a keyboard/synth to play songs when guitar isn’t necessary and this rules. Most apps offer a few sounds for free. This one has HUNDREDS. I will be spending a lot of time on this synth. I thank you. My wife and kids, not so much.

Fantastic APP!!!. I have tried many iOS synths, and this one ranks with the best PAID synths, I have used. LOVE It!!!!!

The Presets are UNBELIEVABLE. This app is unbelievably great! I’ve on Nay scratched the surface while digging into the presets, and yet I feel like Luke Skywalker taking my first steps into a larger world.

Absolutely wonderful. Thank you so much for sharing all these awesome synths to the song writer community for free! I am so excited to use these for my music!😆

Dark technos purveyor. What is outstanding app not only is this a great sense but to have it all in the control of your hand on your handheld device, I just totally and strongly suggest that the people the geniuses that invented this app invent a controller or a drum machine or a synth of some sort that you can take with you on your shows or sets that you do, I want to thank everybody that was involved in engineering this remarkable synth thank you very much. Forgive me father for I have SYNTH!

Would be 5 stars if keys were bigger on iPhone. Great app, fun with a little midi controller, but when trying to play on the iphone there is no option to make the screen just 5 keys lets say (that I have found). Aside from that love all the voices, all the options, you can dive really deep with this free app.

Amazing sound. Sounds are amazing . This is by far the best synth in the app store.

Just amazing !. A monumental tour-de-force ! Certainly one of the best and most affordable (because it’s free 😉) introduction to the world of synthesizers available today !

An exceptional gift. A user-friendly, great sounding and deep synth… AND open-source! :)

Luscious sounds and sequences .... .. Luscious virtual synth ... portable and full charged with excellent controls .

Powerful. What a powerful and well put together Synth project, well done to all parties who contributed to this venture. Only thing missing is AU support, hope that’s a top priority.

AWESOME.FAT. WARM. FREE.. what more could you ask for? I have been messing around with synthesizers since 1982 and this is the warmest sounding I have heard in a long time.Patches you can easily mess around with and dial sub frequencies into to get super fat and bright anthem tracks or mellow etheral pads you can easily customize. so far every single preset I have tried has instantly spawned a new song. Don't try to wrap your head around the fact that it's free. just download it. Use it. And let's get these presets trending !! Best new addition to my DAW. Thanks!!!

Dat sound. Sounds amazing from the first touch on the keyboard.

Super. Super belle et bonne application merci de partager

Cool beans, awesome sauce at the end of the day fam. Tbh, fam y’all need to get this app at the end of the day fam, only at the end of the day, other times of the day don’t matter. Stay safe, stay woke, and don’t be a Karen ok boomer? Gotta go take a selfie with my Hubby, doggos and fur babies

Wonderful chalanges. I’m new to sync with world. This app is producing much more enjoyment and great learning.

Stable, free, sound quality tbd. So far, I’m impressed

Adsterra is the most preferred ad network for those looking for an alternative to AdSense. Adsterra is the ideal choice for new sites with low daily traffic. In order to advertise on the site in Adsterra, like other ad networks, a certain traffic limit, domain age, etc. is required. There are no strict rules. Sign up!

Wonderful app.. I love that this is voiceover accessible. I don't understand what all the' extra things do, so I wish there had been a tutorial or something, but it's still easy to use and lots of fun, especially for me because I'm blind and have to use the voiceover. I don't even have to turn the voiceover off to use the keyboard, as I must do on other keyboard apps. and the sounds are COOL!!!

Greatest sounding synth on iOS. This is the absolute BEST sounding synth on iOS I’ve found. The quality is amazing, and the features are everything you could possibly want. I look forward to when it gets auv3 support, as that would really help me in my projects. But even so, as the synth currently is, I would give more than 5 stars if I could. Thank you to all those who contribute to its development.

Perfect Synthesizer For Anyone!. I love this app. I have been playing music for about 20 years, but just recently started playing with Pads. I am trying to help enhance the sound at worship services at church. That being said I am on a tight budget. Thanks to this app I don’t have to spend lots of money on a new project I’m messing with. That being said this app has absolutely great sounding synths that sound too great to be free. Highly recommended for anyone!

Drum Pad and Recording. This is the most professional free production app ever! I think if you add the ability to record the audio plus have a drum pad with pitch editing and key and note and all of that on there and a beat grid or whatever you call those that this would be the perfect app for this out of them all and easily make it’s way up the charts! Plus since it would all be free you can just throw some ads in there! Plus you already have apps that cost money!

No reason NOT to have this. This little guy is amazing. I’m a hip hop producer and new to IOS production. I am currently using Blocs Wave and BeatMaker 3 and both are amazing but find instruments to replace my favorite vsts Massive and Serum. Now don’t get me wrong, this AU doesn’t replace those synths for me BUT it is sounds very nice and is inviting to tweak and design my own sounds. I’ve always been a preset guy but this app entices me to dive into it since it seems no company has a product like Massive or Serum.

No reason to buy another synth app🐝🦵🦵. Greatest App Ever Made!!!! This is exactly what the world needed to revolutionize sound making in all its categories. A great big giaNT MASSIVE APPRECIATORY THANKS 🙏 to the developers and any contributors of this unbelievable project!!! I sincerely hope to see more programmers give users a great gift like this but I understand people got to eat also!!! Honestly WOW! Thank you Thank You Thank Thank You everyone involved Thank You Forever

Highly Musical //// Incredible It’s Still FREE!. This is my go-to synth app — as the oscillators are fierce, dynamics are as quick as user’s fingers can allow.... After going down the iPad Music Making rabbit-hole about and for a bit over 3yrs now.... SYNTH ONE is a force to be reckoned with — no doubt it holds up and inspires as much as the iconic synth apps made by the analog greats — and the fact that there is so much FREE is nearly a gesture for world peace and altruism!

So awesome what a great app. This is so good for a free application I can’t believe it. Great sounds and total tweak ability. Even for someone like myself who doesn’t know anything about creating sense, it’s very usable and very fun. I’m going to use it to throw a few back up sounds for our cover band, saving us from buying a synth for this purpose and fitting nicely on to my microphone stand, instead of having to buy a separate keyboard stand…

Best free synthesizer app ever. I really love making music with this free synthesizer app and I recommend this app to everyone. This app is great for people who’s good at music but it’s also great for people that’s never played music before and wanted too Learn. This app has nothing to pay for and has no ads. I recommend this synthesizer app for kids, teenagers and adults. Please don’t buy a synthesizer try synth one first and don’t waste your money without trying synth one first

Superb!. I could not send my praise enough! Glorious application with lots of manual modification possibilities and some very awesome presets! I’m sure there are probably a gazillion synths you could customize with all the toggles and whatnot! I’m not as knowledgeable about such but is there info online? I’d say it’s professionally utilizable for music production and performing/entertainment as well as personal recreational enjoyment. thank y’all for a free application, it is much appreciated!

Audiokit!!. I own all of the apps. Synth one is on of the best synth apps for ios. And I’ll support every app huh all make. I met Aure on the Roland Vg-99 forum years ago, doesn’t matter- I love the open source- let’s get everyone making apps ethos spread by the crew. Unfortunately I don’t have an iPad and my recording Mac is ooold. I wish I could create apps on my iPhone 13. I watch the lessons. Desperately wanting to make my own instruments. 👍🏼👍🏼

Excellent by any measure. I’m a music hobbyist with a couple of decades of dabbling in various synths and DAW applications. AudioKit Synth One is easy to play around with, but offers depth for those who seek it. I’m using it on an iPad with a Roland A-800 and it works flawlessly! The sounds compel me to want to make arrangements using them. Kudos to all those whose time and effort went into making this a showpiece for open source effort!

Won’t quit on iPhone. *EDIT*. I’m sure it’s a bug that’ll be worked out, but the app is not *quite* ready for prime time on the iPhone. Fantastic app though. Thank you, devs! Re-downloaded and poked around a bit more. Seems the only way to quit out with the “swipe up” gesture on iPhone X is actually “swipe sideways”, aka swipe up *in landscape mode*. It’s a minor adjustment to the UI of the iOS when accustomed to swiping up for every other app, but the accommodation is a small price to pay for such a great (and FREE!) app.

Amazingly Powerful. Built from the amazing AudioKit library/framework! Has all the synthesizer functionality you’d generally want! Thank you so much to the developers and AudioKit contributors! My only disappointment is that it doesn’t show up in garageband as a valid Audio Unit; although I may not have something set correctly for this to occur! Highly recommended!

I don’t usually review apps. I have been in the market for a Synth for what feels like ages now either you get a rack and build your own which can get pricey or buy a stock synth and kick yourself later for not getting the features you were hoping for, this app is perfect for anyone wanting to explore a super synth without a crazy price tag. Thanks to all the devs involved in this project! Your work does not go unnoticed

Stellar sound design. This app took a long time in the making, and now I see why! It's absolutely amazing. This beats any synth I've installed, which includes most on the market for iOS (most costing 20$+). Great presets, but the control you have over sound is absolutely astounding. AU capabilities and other up to date music creation tools make this even better. Thanks so much to everyone who worked on this and released it for free :D!!!

Flawed, but more than worth the price. Update: the developers have been in touch and I will be checking out the latest version to see if my note triggering issues have been addressed. Original review: Synth One gets four stars from me simply because it has a lot on offer for being free. However, it has a lot of note triggering bugs, and this gets in the way of having fun playing it. Any other complaints are obscured by this one fatal flaw, and it IS a fatal flaw. If you cannot play a patch without notes getting cut or failing to trigger at all, well, that’s just a failure at step one. Fix those bugs and I’d give this synth a full five stars for the sheer amount of playability on offer for FREE. If this was a paid product, I would not be so kind. Thanks for the limited fun, AudioKit volunteers. That’s a sincere thank you, by the way; not sarcasm.

If One right thing goes. One thing goes right. Audiokit Synth1 is so boss. Absolutely solid,(fun)CTIONAL, versatile AND SONICALLY superior to at the very least HALF of the other synths out there. Don’t subscribe to some sampler farm that’s gonna squeeze you for the privilege of advertising THEIR CONTENT. If you’re interested in the actual craft of synthesized music, look no further. SynthOne is the dynamite among firecrackers.

Great synth, one problem. This is an incredible synth but there’s one problem I’m running into. When using this synth in IAA with FL Studio Mobile, I can only set one preset at a time. So basically all my IAA channels in all my tracks can collectively have only one Synth One preset sound playing at a time, which means I have to go into Synth One every time I switch tracks and change the preset to the one I was using in that song. Anyone got an idea what I’m doing wrong? Or is there no fix?

Nothing better available for the money!. Worth every penny and much more. ;) But seriously a terrific app for anyone who makes or wants to make original music. And by the way, has anyone in the AudioKit community thought about creating an AudioKit DAW so all AudioKit apps would work perfectly within a recording, mixing and sound engineering environment? Think about it!

Phenomenal!. I’m not a musician. I don’t even know how to use a keyboard to put notes together to make a simple tune, but I love this app. I can play with this for hours at a time and not get tired of the incredible flexibility just making what some people might call noise. Thanks for the amazing opportunity to see what can be done with some hard work and super generosity. Love it!!

Addictive. I’ve been playing music since 95 but never messed around mush with the electronics side of it even though I’ve always loved electronics.. just these past months I’ve really started to get into that huge world and this app is an amazing way to freely try and understand how things work with a lot of aspects I never new before.. super excited and many thanks to you

Excited to dive in. I’m impressed with the depth and appreciate the different tunings and how that is laid out as one of the features. I love using this app to show people the difference between a major 3rd based on the harmonic division of overtones vs. an equal tempered major 3rd. I hope to go through the user manual and I know I will get an incredible education. I expect I can use this app to help teach other aspects about sound and music.

The Dirt vs. COVID 19. My bandmate Mike Bell recorded a whole album using this app each from our own perspective homes using, telephones, laptops & iPads. Your app is through the roof brilliant & amazing. Thanks to this wonderful app The Dirt has another Sonic Kitchen of Love record on Band Camp. Mike’s been after me to do another from home album the same way. By now, I’ve compiled quite a huge pile of lyrics & writing &$ am looking at AudioKit Synth One as something I can sing to & use to stay on the beat. Thanks a million.

Great just amazing. Download now there is no reason not to. It is totally free super comprehensive and powerful. Developers I want to say one thing, I would be more than willing to watch ads on this app. If it’s possible to have an “enable adds” button in settings that would give an add every once in a while. I would enable it because I love what you guys are doing and want to do something to help even though I have no money to really donate. Ps is that fm kit coming to iPhone

Idk. • For music producers (or curious people whom simply enjoy dabbling with such apps): I think you really ought to download this app Immediately. • I personally didn’t pay attention to my elementary-nor-middle school music teachers; & In thee last couple weeks it’s had me a bit regretful & frustrated—NEVERTHELESS! Despite my ignorance, When I 1st launched this app I had a whole lot of fun in just playing around with it for approximately a minimum of 1hour, (perhaps 2).

There’s no free lunch, but there is a free app!. A large number of whiz kids, movers and shakers got together and created this free app. It rocks! Very cool indeed😊. Lots of bells and whistle‘s and all sorts of groovy little secret compartments that make bizarre sounds that can be edited to your mad scientist desire. Spread the word, spread the love, and keep your eyeballs peeled for the other apps from these developers. Some releases will be gratis and other releases will be commercial/cost money.

Awesome But. Now look, I just got this app last week. AND ITS ALREADY SO FRICKING GOOD!! I don’t have to- But there is one problem. 😢😢😢😢😢😢😢😢 I- don’t know how to, like, make my own sound for the piano’s voice. If I wanted to insert a vocal for a type of note I pressed, it wouldn’t be happening, bye bye dreams🚫! At least there’s no a- Ads…. Other than that this is a great, NO AD, piano! Someday in the future, though, I wish we could edit the notes! Ompoo out!

Five stars but hoping they expand the save and files capacity. What can one say when an app that is open source is so amazing and so proper for developing ideas and even creating direct sounds to use within music apps or to transfer to a direct digital audio workstation on a computer. Amazing. Keep it up everybody

Amazing app. I really love the functionality of this app the quality sounds how easy it is to use!! I only have one request though. I know that this app wasn’t made For SE screens but I love my phone! Is there a way you can make this app fully functional for the SE at the least add a scrolling function so I can see everything that I’m missing? I’d greatly appreciate that! Again I love this app and would love to be able to include it in my creative process more

for dummies. This is by far and away the best touch instrument I’ve ever used and it’s free. I’m basically an idiot when it comes to synths and midi etc but this thing comes loaded with presets to inspire ideas and templates for creating your own presets. I may be a dummy in a whole lot of areas but economics 101 is not one of them , I’d have paid for this product probably but it’s open source and unless I’m really REALLY high, new sounds are added all the time. Thank you thank you . Sincerely the dummy from Kentucky

Epic Synth and an Epic purpose. One of the things that has been quite challenging is finding a quality synth at a reasonable price. As a beginner I don't know if this is truly my calling and shelling out $100 just doesn't seem worth it, no matter how good it is. This synth has more features and a huge community of people willing to share in their experience and knowlege, from all over. If your even thinking about grabbing, just do it, ya got nothing at all to lose

I am Truly Thankful. I am truly thankful for this piece of Extroadinare, in the form of a synthesizer,it’s fidelity is in the league of the fidelity that accompanies the Best of synth..I’m a seasoned musician and long time engineer , I’ve heard the best .I am world traveled .The concept of all involved in the production of this SPECIAL work the touches my heart and emotions..I pray to be worthy of this FREE GIFT...Thanks you ; StanS Stokes (multi horn iInstrumentalist ) studio engineer..

Functional Link automatically gives 3 stars. But this app has everything and the interface functions smoooth to the touch. This is important to me. The sounds behave rationally also. For a free synth it is far and away the best app to have on the iPad. Would love to be able to play with the tunings section. Also it is sort of annoying scrolling around in that section. A revamp of some kind would be nice.

great free app. love this free app and thanks for making it available! obviously maybe synth related yet trying to find percussive instruments nevertheless within it.. hope eventually you guys would consider this within the app as far as percussive additions. but just great sounds depending on taste and way better then let’s say GarageBand [tho not hating on them cause I still will use them to record into from here but as far as quality of sound and just the look of the his synthoneapp is top notch for the nothing paid for or even if a few was attached. great stuff useful to anyone new or more experienced I think!

Hats Off To The AudioKit Team & Contributors. Wow! I came across this app by chance. I am SOOO glad I did. So much synthy goodness packed into one app! No in app purchases and nonsense make Synth One a music production powerhouse without any distractions or annoying pop-ups. Also, the story of how the app came to be is a feel good story that I think anyone can feel. Thanks AudioKit and all the volunteers who have contributed to bringing such a wonderful app into the world! Hats off to you all!

Overwhelming Possibilties. Lots of overwhelming possibilities of sound and melody. I’m already in production of finishing up a song. This is one of many great apps out there and well worth it. It does take time to play around with similar to that of Abelton. The only problem which isn’t even the app itself is, I have no clue what to do as far as copyrighting my own music, where to go, worried people are just gonna steal my music anyways and claim it as their own.

Thank you! It’s totally radical. I’m in the middle of a tough life transition. This thing is giving me another creative outlet that I needed. Something to get me out of my head and into a different vibe when I’m feeling overwhelmed. It’s beautiful and it’s bringing me back to my 80s youth, where I would spend hours experimenting with something and getting lost in the moment.

LOVE this synth!. It’s free, which is awesome, but it’s not just that. A lot of time and thought clearly went into it. The interface is clear, easy to use and attractive. It was a bunch of good sounds and it’s easy to modify or program your own. Plus, if you’re not a sound designer (I’m sure not!), there’s already a community of designers who are releasing additional presets for free! Basically, if you’ve got room on your device- and it’s not too big - there’s almost no reason not to get this app. 🙂

Amazing but here’s some suggestions. This is the best synthesizer app ever, quality synth like this would be like $20 but this app drains battery super fast, also there’s a bug on the app when you open the app with headphones then when the app has loaded and you takeout the headphones and play a note it crashes same for the other way around but overall it’s amazing

Thank you for your service. This app single-handedly allowed me to learn synthesis. It is so intuitive and widely-ecompasing. I use this app to creat sounds on the fly and then I program them into my DAW plugins later using the same settings. This app has so much value and it’s free and no adds, bless the developers they’ve done us a huge service.

Take the plunge!. I had been interested in exploring synthesizers for years, but the learning curve and the price prevented me from doing so. Audiokit’s Synth One solved both problems immediately. It’s super user-friendly: you don’t/won’t need expert knowledge to begin your sonic experimentations right away, and yet it’s powerful and professional enough that experienced synthesists will, I suspect, find ample creative possibilities here too. Kudos to the AK crew for putting this labor of love together!

Better Sounds Than A lot of Paid Products. Many soft synths feature sounds lacking in quality and often feature presets which sound awfully similar to each other. This synth breaks the cycle with rich sounds worthy of high production and successive sounds that are clearly different. Well done.

Developer please read. The reason I’m writing this review is because although I love the app, I’ve found a few issues. 1) The app crashes frequently. Must fix 2) The interface needs an adjustment (simpler interface, better [more straightforward] controls and adjustments, user created sounds, songs, presets, etc) 3) Needs a full keyboard If you could fix these issues and make some additions, then I think that you’ll have earned that fifth and final star.

Great fun!. I am a professional keyboardist have been using synths since about 1976 when I purchased a ARP Odyssey. I never could have imagined that I would be playing a Synthesizer from a hand held device let alone a free app. You guys have created a wonderful useful tool for many people to have access to. Thanks for your innovations and professionalism. Bravo!

The Standard for Synth. This app is absolutely brilliant. I have not made music in years and this reignited the ease of having a piece in my mind and getting it out fast. Even more importantly, it’s loaded with incredible presets that fuel creative immediately. The fact that’s it’s free safe clean and functional is beyond what anyone used to expect. Synth One has set the gold standard for mobile synth, and all or free. Bravo.

Wonderful Sound. I appreciate the depth of sound one can get from this synthesizer. It’s simply well designed and fun to experiment with. The fact that it’s Open Source and completely free is intriguing as well as good for the music community as a whole. Sometimes it’s difficult for people who want a creative outlet, but have very little to no funds to support their endeavor, to find ways to make music; this app is more important than it may seem.

Holy Smokes. I have been making music (soundscapes) on iOS for five years and during that time I’ve tried or purchased almost every synth available. Many of them are great, but none are quite as uniquely, creatively, powerfully and intuitively configured as this one. And it sounds phenomenal. Incredibly grateful to all the people who put in time and effort to make this app possible and free(!).

Above and Beyond. I am a collector and have over 200 of the best synthesizers from classic Oberheims to 2022 Rolands and SCI’s and everything in between and I can assure you that this particular app impressed me. It’s sound and abilities, the appreciator and patches are so carefully chosen. I am thinking about using it as a center synth for a new video I’m going to make. This is one of my top 3 picks for app synths.

Cheers!. Stellar. The program is so full of gadgets to perfect what focus you might want to experiment with. My favorite so far is the fact that someone actually used the sound wave symbols for what KIND of sound was associated with WHAT KIND of wave is made when THAT sound is selected! Joy! I can even do sound experiments now that it compliant with two I’ve never had the time to pair! I LOVE THIS APP. How SWEET and FANTASTIC the developing body of beings are for creating this to share!!!
