(10) One potentiometer for internal clock rate (if onboard clock is used // 11 SPDT switches 1 rotary switch, 5+ positions 6 sockets Potentiometers: One potentiometer per step, to enable/disable gate per the Eurorack standard Outputs saw, triangle, and square waves, with CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in implement a DC offset via non-inverting op-amp. - A CV in to pause the clock oscillilator an external CV-to-pulse-rate module? Is this even useful? Seven-segment display.
