Microcontroller but no DAC. Also interesting UI, featuring lit pushbuttons in a circuit outside the full dev board (in some cases) Arduino + DAC https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on the 16-pin IDC connector when nothing is plugged into it. - Manual one-step-forward via momentary push button. CV out, with probably +12v gates. - Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). External reset via momentary push button. Play continuously or play once (switch to select segments from each step. UI: One potentiometer per step, to set output voltages. (10) One potentiometer for internal clock rate.
