Steps, but limited by decade counter expects CLOCK to pass 1/2 of V+ (i.e. 6v) but many external clock sources cycle between 0v and 5v or even much less. - One potentiometer for internal clock rate. - One per step, to set output voltages. (10) One potentiometer for internal clock rate. One potentiometer per step, to enable/disable gate per step. (10 One potentiometer for internal clock rate. One SPDT switch to disable reset (run once). Momentary-normal-off pushbutton to manually step. SPST switch to adjust parameters for. 1.0 2012-03-??
