Will a Yamaha expression pedal work on a non-Yamaha MIDI keyboard? It uses a stereo
1/4" plug.
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.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

A RTS pedal simply re-labels R and T.
Set the pedal mid-way, set meter to KOhms, measure resistance between
sleeve and ring, sleeve and tip.
You should find one if about half of the other (if a log pot it may be
way off half, but at least less
than.) The lower reading is the slider. Either way, the best way to test
is to simply try it.

Now I just need to track down a weighted, 88-key, MIDI controller with
aftertouch and an assortment of pitch bend wheels, knobs, sliders and pads.
I was going to get an Akai MPK-88 several years ago, but they're no
longer made, and Akai no longer offers anything with 88 keys.
Others on the list:
M-Audio Hammer 88 Pro
StudioLogic SL88 Studio USB MIDI controller
Arturia KeyLab 88 USB MIDI Keyboard
I'm not looking for a synthesizer keyboard with its own sounds.
Ideas?
