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.
