Wow! I FINALLY found an Alchemy replacement!. ... and I like this better than Alchemy!!! So, I am one of the hundreds who are not a big GarageBand fan and feel like they ruined my go-to synth when they acquired Alchemy. Since then I’ve been looking for a replacement or alternative. I only learned about this app when I saw Magellan in an N-track Studio midi tutorial. Luckily, I found it for iPhone as Magellan Jr. and grabbed it right up. Curious, I had to check out the other apps from this designer. The video demo on the app page for Magellan sold it for me. I’ve bought it and fell in love with it in minutes. I am so over Alchemy now that I’ll never use it again now that I have Magellan!’n

Strange behavior, no tech support. I adjusted the filter, including the adsr to something approximating a brass sound, with Osc 2 and 3 off. Then I applied some glide and suddenly the sounds became low volume beeps and there was no way to recover, no reset to default seems to exist, couldn’t find it in the manual either. Exit the app,leave it alone for 24 hr, and it seems fine, glide works the way it should. After reading the manual, which is more of a list than explanation, I got more ambitious and added the other Oscs, fooled around with the second set of adsr and drift and voices, things seemed to work, although the second adsr set is a bit weird. I had written to Yonac about Kauldron a week before, got no form reply nor tech support. I think I could rate this app four if I thought there was any support. I haven’t tried presets yet but I think I will have to, because the app certainly doesn’t load with your last settings, in fact some knobs are not where you would think they would be and others have stayed where they were. Default behavior and reset are not in the manual, nor is there a a good discussion of all adsr behavior. The filter settings don’t have any meaningful indices that I can see, you don’t know where the resonance is, and there is only one (steep) roll off so you really can’t do brass effectively. EDIT: I have again used the Yonac website contact form and received no acknowledgement or response, so I have to conclude that there is NO tech support, so I have reduced my rating to one star, because you can’t do no stars. Second EDIT: I actually got a response after two days, to my 3rd email, but the tech seems not to have read the manual. I have replied but don’t have much hope for a real answer. Third Edit: I have written to Yonac at least four times, and received one reply mentioned above, so I really can’t understand all the rave reviews, the ADSR is goofy and uncalibratable, for instance if you set what you would think is a very short attack and set what Yonac says is a high amplitude, it takes seconds for a tone to reach peak. This is ridiculous. Fourth edit: There is no version history, there is no tech support, I have to believe this app has been abandoned. You can not get into the Yonac forum on iOS, but I have posted from my Mac and there have been a few views but no response, so I have to think that it didn’t sell, and that some of the problems I have described have been experienced by other who also got no response and deleted the app. I am not ready to give up on it, but I am absolutely you can not synth brass adequately, because the adsr is crazy, the cutoff is way too steep, and you can’t place the resonance with any certainty. There does not seem to be a brass instrument in any of the many presets , which would seem to make my point. I notice there are only a few developer responses in the reviews and they are all canned.

You know you want to buy this. Go for it! 😉. You think you already own way too many iOS synths and can't justify buying another one? Well think again and grab this awesome powerhouse while it still only costs 4 bucks. Amazing set of presets and a really useful Spawn button to generate even more. But also deep diving into the knob settings will almost instantly render great results. This synth is a beast and i am glad i added it to my vast collection of synth apps. I don't own any real analog hardware synths so i cannot judge how realistic organic this one sounds, but regardless i think the sounds that come out of this synth are really great and very useful in a musical way. The programmable arp is great too. Just grab it. You know you want it!

Very impressed!. This is amazing! I wrote a patch and saved it immediately! A very good sign! Thank you! Yonac! Peace Christo 🛸🎶👽✌🏻👍🏻

Another winner. Deep sound engine I love it! Easy to program easy to go to new sonic places. Keep up the great work!

Yonac: Master Synth Creator. Nuf.

A stunner at the price, but in the scheme of things.... Quality-made, well-functioning app, but lacks the oomph of Model 15 and Zeeon, the analog-modeling standard bearers. Like Kaspar, in my opinion this synth is lacking in personality. Just like the other, it has a hard-to-describe ‘sheen’ to it that keeps the synth from busting out and sounding truly organic. There’s no oomph. Having owned all the other Yonac synths, this is something common between them all, so if you’ve liked that ‘Yonac sound’ in the past, I’m sure you’ll be satisfied. Still, this doesn’t offer anything new other than an excellent random feature. I don’t think you can do better for $4, but at regular price ($10), see Zeeon for your analog-modeling needs.

Awesome.. Everything by Yonac is superb. Stop reading and buy it.

Powerful, stable and rich.. Kauldron is an incredible synthesizer! Three OSCs, an arpeggiator, extensive effects and modulation capabilities... look, it’s $10. Buy it.

Needs updating. Midi learn functions not saved. Am I missing something? Sometimes glitchy

Always. I’m always highly impressed by this team . I get everything without thinking twice if I see who made it and it’s one of 3 who’s constantly solid and innovative. This is a company who does everything with depth and consideration.

Fail, if you use a iconnectivy interface. I have a lot of synth apps, and they all work with iconnectivity....except this one. So it’s worthless to me. If they convince me it does work, then prove it and I’ll change my rating.

Realistic Analog Sound. This synth has a very expensive sound quality, one of the best on the appstore. Just amazing!

Both Magellan And Kaspar are better. Overhyped... Uninstalled. I own every Yonac app and IAP... You can skip this one unless you like the idea of the Yonac sound sans what it’s other synths bring to the table but.with AU thrown in (even the Randomizer on this one isn’t as good as the one on Magellan... or maybe it’s just that it has less to work with).

So far so good on iOS 10. Will this work with iOS 12 ???

I misjudged this synth. Its brilliant (rewritten review). First off I respect Yonac immensely and always support their products. Tonestack and magellan are two of my most used apps. They run brilliantly, sound amazing and are incredibly cpu efficient. Kauldron is definitely going for a very punchy, detuned and saturated sound --which if that's your bit then I think you'll be very pleased indeed. The tone sounds more "aggressive" than magellan. I misjudged this synth at first and didn't realize how deep it was. Really blown away and it offers stuff sonically that I didn't realize as brilliant at first. Now my complaints. Magellan jr had a much larger sonic palate in my opinion. The patches in kauldron (including my own experimenting) sound more niche to me. Also most patches sound as if they're going thru a cab simulator which could be a bad or a good thing depending on what you want. The other thing is magellan had more options in terms of fx and also multiple filters routing etc. But it is a different beast that I have grown to love in a different way. Still hoping for megallan 2 tho! The other complaint is that the new spawn has a basic mode with no PAD, LEADS, BASS options and then a very confusing somewhat unpredictable advanced mode. Not really sure what any of the controls or modes mean even after using tutorials. Autonomy vs variation? Please relabel All around this this synth can produce some really unique sounds I haven't really heard anywhere else. Keep em coming yonac!

An outstanding offering from a brillant developer. Even at a multiple of the $3.99 into price, Kaudron is a powerhouse of an iOS synth, with a boatload of tone generation, sculpting and performance features. It sounds THICK as a wall made of iron, tons of analog vibe, deep programmability, excellent AU implementation, tons of presets, and did I mention it sounds as thick as a planet made of marzipan, concrete and diamonds, with unlimited musical possibilities? I pretty much buy whatever Yonac releases, but this one has to be the most effortless purchase so far. If you're into iOS music making, don't even hesitate, get it, you will NOT regret it.

Omg thank you for these presets! Woot!!. One of the more exciting new synths out there and you don't have to be a professional sound designer to get started (though you could be lol). PLUS the PRICE IS IRRESISTIBLE. ...And if you know Magellan, you know they make great synths. Yeay!!

Modulation. How do you define Mod control 1-4 in the modulation matrix?

The best Yonac synth. Why? Lots of great presets, Spawn2, not overly complicated interface, great sound, AU, awesome arp. My go-to synth these days.

Yes!!!. Guitars, organs, Kauldron, and magical connotations. Tobacco is good company to keep!

Awesome IOS Synth. Yonac, this App is the Bomb!!!! Love all your feature rich synth apps. Again, you hit this one out of the park. So easy to use, n yet so much to tweak so to develop ones own sounds. Thank you Yonac,

Still no fix for the AUv3 bug. Kauldron is a great standalone iOS synth. Unfortunately, it’s effectively useless as a plugin due to a bug that I reported over a year ago. When loaded as an AUv3 (I’ve tried it in BeatMaker 3, GarageBand, NanoStudio 2) with a MIDI keyboard connected over Lightning, Kauldron doesn’t conform to the standard behavior of only receiving MIDI notes when its track is selected. Instead, it receives notes regardless of the current track. So if you record a bass line with Kauldron and then try to record a lead with Zeeon, Model 15, or any other AUv3, your lead also triggers notes on Kauldron. As I said above, I reported this bug over a year ago, and never received a response. It’s disappointing because Kauldron sounds great! I’d love to use it in my iOS production, but I can’t with this workflow-breaking bug.

Great little synth. Sounds nice, controls laid out well... but above all for me it runs like a dream as an a AU plug in in Cubasis. Low cpu hit, GUI is easy to access. Thank goodness Yonac showed how it should work! I haven’t been able to record the movements of the XY pads as automation in Cubasis yet ... not sure if it’s not supported within Kauldron, or if something else is in play. But if you are trying to go all AU and get rid of all the IAA / routing headaches then try this. Let me play around a bit mote and see if the extra star is forthcoming!

Great synth. This synth sounds absolutely killer, and you can arpeggiate anything with ease. Love it, thank you!!!

Omg cyber Monday. Whaaat? $$ insane cyber Monday deals! The Yonac synthesizers sound incredible! Magellan, Kauldron and Kaspar are iOS must-have synths. Just paid eight bucks for all three sonic powerhouses. Ableton Link provides sync for controlled analogue mayhem. Thank you Yonac 🎧🎹🔥🔥

Poly Aftertouch Dream. An amazing app from very a talented developer. Works fantastic with my Kurzweil MIDIBoard. The sounds are all very distinctive in an interface that is at once intuitive and powerful.

Won’t load into Logic Pro. It’s been working and all the sudden today it says it can’t load into Logic Pro and to contact the manufacturer.

Fantastic sounds!. Kauldron sounds fantastic! The “Maximizer” along with the new “Spawn2” Randomizer (especially with the arp) make this somewhat standard functionality app well worth the introductory price. On top of these excellent features, the latest technologies (AUv3, full-screen AU, AB3, complete MIDI mapping, etc) make this a most competitive synth at “full” price which is still a bargain compared to desktop synths and plugins. Get it NOW - you won’t be disappointed.

One of my top favs. Though it looks like a simple synth at first glance, it can deliver a good range of sounds. I wouldn’t say it’s my fav synth as it’s hard to judge, but it’s definitely in a group of my faves. Efficient, has a character, easy/pleasant to use, good sound quality, good presets management (can create banks and rearrange slot-based patches). Has AUv3. Another excellent synth from these guys is Magellan 2, both are must-have, imho. Very pleasant to use, feels like hardware.

.... A Beast Synth 🔥🔥🔥💪💪💪!!!. I been using Yonac synth for a few years now , very complete suite for music 🎶 production , especially if you are looking for mobility. Magellan is my favorite of all , Kauldron and Kaspar are powerful enough but - the don’t have a sequencer , Magellan does . Very easy to create Unique Samples and send them via email to Desktop DAW. I also miss the browser download which Magellan has , much simpler to send for large audio files . The SPAWN feature is a Beast 🔥🔥🔥 I been creating original effects for my Trance Music 🎼 project in a Breeze. I hope Yonac bring a DrumMachine , PAD Launcher and DAW to their product line.

Great Presets. I love the presets and the filter pads are easy to use!

Great - another great synth from Yonac. First impression - Very happy with purchase, straightforward GUI, great sounds and features. Never disappointed with any app Yonac offers.

Good synth. Happy with this synth from yonac. I uninstalled Magellan coz it was getting a bit outdated by a lot of the newer synth apps. But this is a keeper. Very good sounds. Basses are fat and the arpeggiator is neat. Spawn2 will be well used. Nice work devs.

Another winner for Yonac. I purchased Kauldron after using Kaspar for a while. Based on my excellent experience with another product, I bought this one, if only as a thank you for the fantastic development effort! Lo and behold, Kauldron is just as fantastic as Kaspar, yet different. Worth it just for Spawn 2 (even if some of the generated sounds are unusable, except perhaps in an attempt to summon Slaneesh...) as an example of how a “randomizer” should work. Excellent work once again, devs! Thank you and please take more of my money, you’ve earned it! PS: You know, if you considered building an effects tool of some type, with the skill you’ve demonstrated, I’m quite sure you’d get more of our money!

5ive ⭐️. The title says it all...this synth is fantastic and comes loaded with lots of room to maneuver...way to go Yonac and freinds!

This one is very beautiful.... Just as Magelan is. But I do not like very much overall sound of YONAC’s synthesizers. The sound is dull a bit. Of course you can fix the sound after some tweaking, make the sound brighter, happier, dancing on the oscillator’s wind etc. So everything looks beautiful except presets. Of course this is just my opinion. I recommend you to buy this beautiful synthesizer and try it for yourself. The price is right and the file is small.

Stunning ‘analogue’ synth. I have most of the iOS synths available - various Korgs, iVCS3, Moog model 15, Yonac’s other synths, etc. When this appeared on offer today at less than $6 CAD, I bought it without even checking for reviews, and even after just checking the presets I was more than happy - this is a powerful yet easy to program analogue beast that can also produce sounds that many a digital FM synth would be proud of. After an hour or so of tweaking knobs, I then checked out the SPAWN auto patch create panel, and wow. It can of course create sounds that are unusable, even inaudible, but it also produces patches that have me wondering how it’s done. A no brainer for synth fans even at full price, get it while on offer and you’ll have even more reason to smile.

Fun fun fun TIL my daddy took the T-Bird away. Kauldron is special. Yonac stuff is all incredible. They do not make mediocre apps, only great ones. One of the first was Magellan, which, I am sure everyone will agree is an epic synth that belongs in every IOS device belonging to every music maker. After Magellan came others that are all great in their own ways. I do not think when I see a new app from Yonac; I react on instinct and purchase it as quickly as I can, so I can open it and immediately start having fun. Kauldron is not only great like the others but it has Spawn2. Spawn2, Spawn2, and more Spawn2 has contributed to my happiness level greatly. Oh boy, will you ever enjoy Kauldron. There is no choice, so if you do not like to have fun then forget it because Kauldron has advanced fun features that can not be turned off. The only way to stop it is to close the app. The problem is that the temptation to continue having fun is too much for us ordinary mortals. Try the advanced midi stuff to control any setting. I use the midiLFOS APP. Sooo much endless fun with incredible sounds. Kauldron is a huge winner.
