M20SIX v1.0 is an original open-source performance synthesizer, sequencer and programmable drum machine for the Critter & Guitari Organelle S2, created by Pascal Glenn.

It combines a PolySix-inspired polyphonic synthesizer, MS-20-inspired filter character, A/B/AB melodic sequencing, arpeggiator, effects and an integrated six-voice programmable drum machine.

Drum voices: Kick, Snare, Closed Hat, Open Hat, Clap and Tom.

The drum machine includes 16-step A/B/AB programming, accents, mute, finger drumming, live recording and 8 factory drum grooves.

M20SIX also includes 100 permanent USER memories which save the complete performance: synth sound, melodic sequences, drum patterns, BPM, swing, effects and arpeggiator settings.

The included README explains all controls in detail, including exact AUX + wooden key combinations for sequencing, drum programming, SAVE/LOAD and navigation.
