External reset via momentary push button. - CV out, with probably +12v gates. Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). - External reset via socket. External reset via momentary push button. - CV version maybe possible, but a much bigger circuit.
