Yonac has released Kauldron, a new synthesizer instrument that offers analog-modeling, punchy and honest synth tones, a superb selection of modulation options, revolutionary A.I. based preset generation, and universal & AUv3 plugin all in one package.

Yonac Kauldron

Yonac has been working long and hard to develop Kauldron’s completely new virtual-analog technology, resulting in its warmest, punchiest synth to date.

We augmented this by designing many brand new features, so that big synth sounds come easily. Full of rich, complex analog textures yet deceptively easy to use, Kauldron is a pure, honest synthesizer that requires little help from FX or post-production to take centerstage.

Kauldron can run natively on iPad and iPhone, as well as an Audio Unit plugin. It is the first fullscreen AUv3 plugin for iOS, allowing you to enjoy all of Kauldron’s features on a nice, big spread.

Kauldron also debuts the next generation of Yonac’s 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!
