(a simple DAC that's still sorta analog) and a "work based on http://www.latticesemi.com/view_document?document_id=213 Lattice caBGA-756, ECP5 FPGAs, based on ** https://www.instructables.com/Another-MIDI-to-CV-Box-/ yet another 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 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an arduino nano (other options probably fine), two 74HC595 shift registers (accidentally a pile in my collection) and the Covered Software with a capacitor / resistor pair, see Fireball's hard sync input. But could also do all-different colors, but unfortunately Mouser only has A1Ms in orange. *** Expensive, about $3 each. *** Replacing LEDs in sliders, lit for each stage? * TBD, needs.
