Will a Yamaha expression pedal work on a non-Yamaha MIDI keyboard? It

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.
-a.
For this sort of thing, and testing leads, PSU polarity etc. a small cheap
meter is invaluable. Takes all the guesswork out of it - so you see what you
*actually* have, not what it says it has!
I have a meter. Will just have to figure out how to test this using it!
