Kauldron is our warmest sounding, punchiest synth yet! A completely new modeling technology, combined with carefully designed features help you create aggressive synth sounds full of rich analog textures with the fewest knob tweaks. The result is a pure, head-on tone that requires little or no FX or post-production to sound big.
Kauldron pushes every available iOS technology to the max: it is not only fully universal (you can run it natively on your iPad and iPhone), but also an Audio Unit plugin. In fact, it is one of the first fullscreen AUv3 plugins for iOS: with iOS 11 and a compatible DAW, you can enjoy all the great Kauldron features on a nice, big spread.
Kauldron debuts the next generation of our Artificial Intelligence preset creation system, SPAWN². Completely reimagining the groundbreaking SPAWN algorithms in our hugely popular Magellan, the new SPAWN² gives you unprecedented control over generating presets. In the expert mode, you can accomplish anything from subtle ‘variations on a theme’ to bold new sounds. In the basic mode, where Kauldron does all the thinking, you get preset after usable preset with just a touch. This is not simple randomization: it is the power of machine learning put to benevolent use!
Kauldron is designed with modulation and fine dynamic control in mind. The two fully-featured LFOs and the mod envelope combine with a wide variety of MIDI learnable controls to manipulate multiple parameters. Everything is easily set up in a clearly laid out ‘mod matrix.’ The dual XY-pads can be used for controlling modulation or a wide range of synth parameters. MIDI aftertouch can be routed via the matrix for even greater control over expression and tonality.
Powerful arp with both live & program modes; comprehensive MIDI features with effortless MIDI learn; over 900 presets; recording, sharing, IAA, Audiobus 3, Ableton Link — these are just some of the features brewing inside Yonac’s Kauldron.

Ratings and Reviews
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.
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.

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 in a group of 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 good synth from these guys is Magellan, but that one doesn’t have AUv3, otherwise it would be part of my faves too. But if you don’t care about AU, do check it out. Anyway it’s too cheap to pass by. Very pleasant to use, feels like hardware.
