Consider adding a switch to disable clock (pause). - SPST switch per step, to enable/disable gate per the Eurorack standard Outputs saw, triangle, and square waves, with CV in to pause the clock Add CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in to pause the clock.
