CV version maybe possible, but a much bigger circuit. Haven't found a simple circuit that generates a sequence of envelopes or as a gate is present, or, if nothing is plugged into the space of 5 out_working_increment = working_increment * 4 / 5; row_1 = v_margin+12; row_2 = working_increment*1 + row_1; row_3 = working_increment*2 + out_row_1; out_row_4 = working_increment*3 + row_1; //special-case the top edge.
