Probably can't do, or impractical: CV-controlled clock. Presumably the 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 notable issue with this design is ancient; maybe an updated one exists with current ICs?
