The weird little synth that earned its cult. Digital oscillator engines run from wavetable through speech to physical modelling, then feed a real analog filter — a pairing that keeps the strange sounds warm. Four-voice paraphony, a mod matrix, and a sequencer with randomisation baked in mean the happy accidents arrive on schedule.

The flat capacitive keyboard divides people: no moving keys, but polyphonic aftertouch — rare on any synth, let alone at this price. Treat it as a new instrument rather than a worse piano and it starts paying out.

CV/gate and MIDI make it a good citizen in a bigger rig. If a synth should surprise you at least once per session, this is the one on our shelf that does.
