I don't think you understand what I posted earlier... You don't need to keep your foot on the switch ! Just press it once briefly to activate the particular function which you have selected for the footswitch.... For example : If you have selected the Start/Stop option, then one brief press of the switch will Start the rhythm going and another brief press will Stop the rhythm. If you've selected Intro/Ending then the first press of the footswitch will start the selected Intro and the next press of the switch will initiate the Ending process......
This will only work with a footswitch which is NON-Latching.... From your initial post, it would seem that your switch is a Latching type.
To see if you have a compatible footswitch, you need to check across the Jack plug for a circuit when the switch is pressed and no circuit when it is subsequently released......
