Inspired by the elusive RSF Polykobol from the 1980s, this synth revives a forgotten analog legend with modern twists like full MPE and poly aftertouch, letting each finger dance independently across eight voices.

The Mk2 edition packs a compact desktop chassis measuring just 465 x 178 x 51mm, with an intuitive front panel of knobs and switches for hands-on tweaking. Dual VCOs per voice—using reliable AS3340 chips—morph seamlessly from sine and triangle through sawtooth to variable pulse width, plus a suboscillator and noise for grit; hard sync options between them add bite. A creamy 24dB/oct lowpass filter, built on the SSI2144 chip, handles cutoff, resonance, and key tracking, while velocity and aftertouch directly attenuate those for instant expression. Two digital ADSR envelopes (one for VCA, the other cycling for filter and more) pair with dual LFOs offering sine, triangle, saw, ramp, square, or random shapes, each with AR envelopes and routing to up to eight destinations like pitch, waveshape, sub amount, or FM via VCO2. A deep mod matrix expands this with bipolar controls, 384 presets, microtuning, and global portamento, all fed through a mono 1/4" out and headphone jack with USB/DIN MIDI.

Players love its evolving timbres and playable responsiveness—perfect for live sets or sound design—though some note the digital LFOs can feel less organic than pure analog paths. It's a standout in Black Corporation's lineup, bridging vintage vibe with today's expressive controllers.
