It would be cool to have active step, like the monotribe- even better would be individual active step for each part, so we can make polyrhythms
Also, programmable gate-time and pitch for individual steps (like on the EA-1) would be great. It would be cool to set the gate length with button press (i.e. the strip of sound selector buttons indicate gate length 1-8) rather than decimal values on the rotary encoder.
combine (ring mod) audio inputs with all four synth voices perhaps?
Filter envelope would be nice too, if it’s hidden there somewhere on the main board.
