An expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Everything by Hagiwo (quantizer, filters, noisemakers, etc MIDI-to-CV, either over USB or directly over 5-pin DIN (with optoisolator) What we build next? Pretty confident we do know we need a bigger flat flat_size = 5 square(top_rounding_radius + pad, top_rounding_radius + pad); circle(r = top_rounding_radius, $fn = knob_faces); // @todo Calculate the convexity values based on https://www.schmitzbits.de/ms20.html which is a guessed value; could be other values, ceramic may work, test debouncing. Maybe enlarge footprint if needed.
