Kauldron Synthesizer

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.

Reviews

Poly Aftertouch Dream
dnylsun

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.


Powerful, stable and rich.
GrahamBablam

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


Modulation
Tigerfrost309

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


wow for 99c ?
Nosidel Montesino

im lucky that i was looking around the app store and i came across this 12 anniversary 99c all apps one day deal, thank you so much for this great gift


Great Presets
twnshp4000

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


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.


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.


Wow! Yonac is the Flagship ISO Synth Developer!
Thirdnail

Yonac has never failed to deliver amazing synths. The sounds are lush and inspiring. The tweak-ability allows even the pickiest of us to dig our heels in and get dirty, yet basic enough for beginners to get right to the meat of the sound. The prepackaged presets cover every need imaginable as does KASPAR and Magellan... Yonac just nails quality, ease of use, value, beautiful user interfaces and rich sounds. Thank you Yonac, I will spend many hours playing with this!


Great synth
slyone97

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


Awesome IOS Synth
billyboyannap

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,
