Read full description

Kauldron is where classic warmth meets Artificial Intelligence. One of our toniest and punchiest synths, Kauldron features a completely new analog modeling technology. The full spectrum of rich synth textures is bolstered by the groundbreaking SPAWN intelligent preset generation system that allows new patches to be created at the touch of a button. Abounding with pure hard-hitting tones, Kauldron requires little to no FX or production gimmicks to sound big. 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. Kauldron also 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 A.I. put to benevolent use! Kauldron also includes its AUv3 plugin version so that you can seamlessly run multiple instances in your favorite DAW. Powerful arp with both live & program modes; comprehensive MIDI features with effortless MIDI learn; over 900 presets; recording, sharing, these are just some of the features brewing inside Yonac’s Kauldron. Selected specs include, SYNTH • 3 analog modeling oscillators w/ multiple waveforms & true PWM • FM via Osc 2 • Maximizer module with drift, spread & voice count for huge, stereophonic all-synth sounds • New vAnalog filter design w/ ‘dirt’ overload for even warmer, harmonically complex tones • Dedicated filter ADSR envelope • Filter tracking, contour & more • Pink/white noise generator • Osc. phase reset & sync • Retro & modern glide algorithms • Virtual VCA envelope with 2 attack types • Poly/mono operation • Legato mode for buttery smooth passages • Extensive modulation options via the ‘mod matrix’ • 2 LFOs w/ BPM sync, keytracking, trigger mode & more • Assignable mod envelope • 23 mod targets • 11 mod controllers, including aftertouch, velocity & keytracking • 2 XY-Pads for controlling mod targets or synth parameters • Arpeggiator with live & program modes, 11 algorithms, gate, swing, note value, octaving & more • Stereo mod effect with chorus & flanger modes • BPM-syncable stereo delay • Studio quality reverb w/ 7 room types, damping, time & mix • 900+ presets in a wide variety of styles & sounds SPAWN² • 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 • AUv3 - use as Audio Unit instrument plugin on iPad & iPhone • Fullscreen AU mode • Extensive MIDI: MIDI learn, aftertouch, MIDI CC map save/share, KB mapping, program changes & more APP • iPhone & iPad Compatibility • Powerful YPAT2 preset management system • Classic or ribbon key controller • Ribbon controller: Poly aftertouch into Kauldron • Ribbon controller: Settable musical key & scale • Classic KB: Velocity w/ sensitivity setting • Tapedeck: Record, loop & share • Metronome • Tap BPM

Continua is a professional synthesizer for iPad, built around a single idea: everything should move. Three oscillators with five modes each — Virtual Analog, Additive, Supersaw, Supersquare, and IXA — give you a palette that runs from warm analog warmth to aggressive digital textures to sounds that have no easy name. Stack 64 sine waves. Detune five sawtooths simultaneously. Explore phase modulation borrowed from a synthesizer most people have never heard of. The oscillators are just the beginning. Continua's filters don't switch between types — they morph between them. Low pass becomes band pass becomes high pass in a continuous sweep, with resonance and two- or four-pole slope selectable at any point. Two filters running in series or parallel, each one a moving target. Modulation is where Continua earns its name. Nearly every parameter is a destination. Every knob can receive up to five simultaneous modulation sources — envelope generators, flexible multi-point envelopes, four shapeable LFOs, sample and hold, and a random source that gives each voice its own personality. Right-click any knob to connect a source. The routing is as deep as you want it to be. New in version 1.2: the Genetics panel lets you evolve your patches through an interactive mutation tree. Start with any sound, explore branches of subtle variations, and drill down into whatever catches your ear. The arpeggiator adds eighteen patterns — from standard ascending runs to Brownian motion and probabilistic rests — all synced to your DAW tempo. Four new oscillator modes expand the raw material available from the ground up. Full MPE support means Continua responds to every dimension of expression from a Linnstrument, Osmose, Roli Seaboard, or any MPE controller. Or play it with a standard keyboard and automate everything else. Works as an AUv3 plugin in Logic Pro, AUM, Cubasis, Drambo, Garage Band, and any AUv3-compatible host. iPad only.
