The same principle would apply to sustain pedals that use potentiometers rather than switches (to be able to do half pedaling). However, you might still be able to use the Roland Triple pedal if you cut off the tip ring sleeve (TRS) jacks and replace them with normal TS 1/4” jacks… as long as you only ask them to do switched functions.



Thanks for that excellent tip Diki.

This gives me a better understanding of why I could not get the Roland unit to work.

I had not thought about converting the TRS jacks on the Roland unit into standard ¼” TS jacks.
