I am trying to set up an external pedal to control the tap delay. Whenever I play live, the clicking noise from the foot switches gets amplified in everyone's monitor. It is not really a problem except for when I need to tap in my delays since you have to tap several times to get it in tempo. It may be an external mic that is picking up my switches, but I figured the easiest thing would be to just plug in an external pedal that is quieter. I have plugged in a down=on up=off switch from my keyboard. I expected this to work, but it doesn't. Any ideas? Is this even possible?
