I had no troubles at all using a volume pedal.

Try having it plugged in when you boot up the keyboard. Same for the sustain pedal. Have it plugged in at bootup and the MS will automatically sense the polarity.

PS Sorry James, I just re-read my post... that was not directed at you..it was for the OP.
