Percussa micro super signal processor

Yonac are one of the original iOS developers. There from almost the very start of the app store, and I think that they were the first to bring a synth to iOS before it was even iOS (it was miniSynth if you’re interested, and is now miniSynth 2). Since then they’ve brough high quality apps to the store on a very regular basis and have developed some of the most innovative apps I’ve seen.

Today they bring us a new synth, Kauldron, which they describe as  “our warmest sounding, punchiest synth yet!” They go on to explain that this new iOS synth is based on a wholly new modeling technology, combined with carefully designed features help users create aggressive synth sounds full of rich analog textures with the fewest knob tweaks.

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.

SPAWN²

Before going into what SPAWN is, I think it’s worth saying that this is one of the most interesting features here, and almost certainly one of the best uses of this kind of AI technology in the synth space, irrespective of whether it’s used in an iOS app or any other operating system for that matter. Here are the details:

  • Automatic preset generation via artificial intelligence
  • Generate infinite new, usable presets at the touch of a button
  • Expert mode lets specify Variation & Autonomy for each major synth module
  • 3 unique A.I. algorithms
  • Auto arp programming in any listed scale

PRO FEATURES

  • Fullscreen AU mode in compatible DAWs & iOS versions
  • Extensive MIDI: MIDI learn, aftertouch, MIDI CC map save/share, KB mapping, program changes & more
  • Inter-App Audio
  • Audiobus 3
  • Ableton Link

Kauldron is supported on iOS 10.3 & newer, and on iPad Air, iPad Mini 2, iPhone 6, 6 Plus, & newer devices.
