Modular Synth VCO Design & Build

Needed an excuse to (finally!) learn KiCAD, so I decided to build a voltage controlled oscillator (sawtooth core). It's inspired by the early Elektor Formant synths, and designed to integrate with existing Eurorack synthesizer systems.

In the video I'll also talk about how I breadboarded up a MIDI to 1V/octave converter to go with it for keyboard/computer control.

See YouTube description for timecodes.

Code I wrote for the PADI IoT stamp in the video for MIDI/CV conversion: https://github.com/schnommus/padi-midi-cv

Hadn't originally planned on publishing a video about this board but I had so much fun with it that I though it was worth making a video about!
