BackAnother 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 LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on EPCOS app note at http://www.cypress.com/file/140006/download DFN, 6 Pin (https://www.diodes.com/assets/Package-Files/U-DFN2020-6%20(Type%20C).pdf), generated with kicad-footprint-generator Hirose DF13 through hole, DF63R-3P-3.96DSA, 3 Pins per row (http://www.molex.com/pdm_docs/sd/460071105_sd.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py ST HLGA, 10 Pin (https://www.analog.com/media/en/package-pcb-resources/package/pkg_pdf/lfcspcp/cp_10_10.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py PowerPAK.
