Fairly simple one, using Arduino (nano or uno) + MCP4725 (DAC). ** https://hkadesign.org.uk/monotronkb.html 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 Kassutronic's KS-20 VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some supporting components. ~$6 in parts, depending on PCB sandwich, making some final-ish decisions about connecting to front panel components and interconnects between middle and bottom offsetToMountHoleCenterX = hp - holeOffset; // 1 rotary switch, 5+ positions 6 sockets Potentiometers: One potentiometer for internal clock signal (possibly external).
