See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages. Needs a 4040 binary counter, but separated quantizer might not https://www.youtube.com/watch?v=3v1yTFsypqA Sample & Hold MK's S&H, though maybe move the arrow shaped cutout in the attack path). Capacitors can be used as a kind of odd LFO.
