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 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an arduino nano clone (atmega 328p), 12-bit dac (mcp4726) and small amounts of supporting hardware Microcontroller and smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a microcontroller but no DAC.
