PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a switch to disable clock (pause). SPST switch to disable clock (pause). SPST switch per step, to set output voltages. (10) One potentiometer for internal clock signal (possibly external). Commonly called a "Baby 8". 0 0 Notes and rhythms for samba reggae.
