For yet another fairly simple one, using Arduino (nano or uno) + MCP4725 (DAC). ** https://hkadesign.org.uk/monotronkb.html for yet another version Alternative: CV from something else VCF MK's Diode Ladder VCF ~$8 in parts, depending on PCB Added input resistor for sync; placed everything on PCB 398c2b234c Checkpoint after tweaking footprints some more, starting over at 14hp Added hard sync input. - Portamento (aka slew rate controller aka glide). - Knob version fairly simple. - CV out, with probably +12v gates. Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use.
