Thank you for this, i’ll have a go at this. This is just a part of the circuit that i couldnt get to work. The output of this is connect to a relay and more circuitry for my ABY pedal design..I would use a jk flip-flop or a discrete latch circuit, then place a logic NAND at the switch to start timing when the switch is closed, reset the latch when times up
I think this will do what you want (from what you described):
It seems weird that you want on/off and reset with just one output, but hey...
