Turns out you can make a perfectly adequate VCA with two diodes and a resistor! Add a transistor and an led for blinkies. Works great for square-ish waves, ok for others. Got the circuit from the hackaday logic noise series. Also: with no LED, it’s passive! You should go build one for your system! #synthdiy #modularsynth #diode #analogElectronics
