C15 (black) w/Flight Case

KeyboardDigitalPolyphonic

Imagine coaxing infinite timbres from just two sine waves— that's the elegant genius at the heart of this synth, where phase modulation and clever feedback unlock everything from glassy pads to metallic stabs without ever needing waveform switches.

Its digital engine powers 20-voice polyphony through dual oscillators (Branch A and B) that cross-modulate via phase, ring mod, or feedback, each feeding shapers with drive, wavefolding, and asymmetry for Buchla-style edge. Signals hit a state variable filter, comb filter for resonant physical modeling vibes, and effects like flanger, delay, reverb, plus a gap filter for stereo tricks—all blended in a feedback mixer that sparks organic chaos. Three ADBDSR envelopes (attack, decay1, breakpoint, decay2, sustain, release) shape it all with velocity and aftertouch sensitivity, while MPE support adds per-note expression.

The 61-key Fatar semi-weighted keybed feels premium, paired with dual 800mm ribbon touch strips (each with 33 LEDs), a dedicated bender input, and four pedal jacks for live control. Detachable base and panel units (OLED display, encoder, 18 buttons) make it stage-ready, and this black edition ships in a rugged flight case. Players love its performative depth and preset quality, though some wish for graphical envelope views—the hands-on flow wins them over anyway.
