Thanks!
Hi,
Some expression pedals are wired with the pot on TRS, some others use
RTS (i.e. wiper of the pot either on tip or ring). To make things worse,
some use a lienar pot, some others use a log pot.
AFAIK Yamaha uses RTS wiring. On the other hand, most pedals use TRS.
But in a lot of keyboards, the polarity is either tunable or
auto-detected.
The only advice is to test the pedal on the keyboard, or to check in
its documentation.
