hi, all i have a time factor delay and a dd7 delay, the thing its i want to control tap tempo with just one switch and the preset with another one, but i want the tap tempo for both pedals to be the same, i have two carling SPSt NO switches, but im no so sure about the wiring, do i connect one switch lugs to tip and ground, so when i push the switch the delay take ground reference to change the tap??, and i put a diode on the second switch for another reference for the delays to know i want to change banks or pressets??, im a bit confused in here, also for the delays wil be the same wiring but different output ans same switches, so the output jacks will be only connected one to each other.
