Smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a microcontroller but no DAC. Also interesting UI, featuring lit pushbuttons in a ring arrangement; a challenging PCB and/or print job! 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 _big_ knob, these are some setup variables...
