The build is pretty straightforward except for mechanical assembly, and one 16-pin IC. But 3 panel-mounted UI elements for every step (plus some others), so plenty of room for a label // internal clock rate. Switches: Momentary-normal-off pushbutton to manually reset. - One potentiometer per step, to set output voltages. (10) One potentiometer per step, to enable/disable gate per step.
