Yamaha PSR-630: Need fix for reversed polarity of sustain pedal

by Jane

Hi,

My name's Jane and I have a PSR-630, and when I use my sustain pedal with it the function is reversed (it sustains when it's in a resting state, and it releases the sustainment when it is depressed). I was wondering if there's a way to reverse the polarity on the sustain pedal input of the keyboard without opening it up and switching wires and stuff. My friend has a Roland, and he can do it just by pushing buttons and changing it on the display.
I was checking the manual of the PSR-630 but I haven't been able to find anything about it in there.

Thanks!

Hi Jane,

If Alfred's advise doesn't work: I'm not familiar with the 630 but in most Yamaha keyboards you can reverse the polarity. Look under function and sustain. You will find the settings there.
Also, normally a factory reset will do the trick.
Hold down the highest white key + the nearest 3 black keys while powering up the keyboard. That will bring it back to 'As from the factory'
MIND!!!! A factory reset will delete everything that might be in USER-area's so you better make a backup first.

Good luck
Dick

Yamaha PSR 630 Sustain Pedal

Dear Jane: Check the pedal, if it has a small switch, flip it to obtain the correct polarity. If the pedal has no switch, do the following:
1) Plug in the pedal BEFORE TURNING YOUR 630 ON.
2) DO NOT PRESS THE PEDAL AGAIN UNTIL YOU ARE READY TO PLAY.
I do not recommend opening the unit for any invasive action. Do me the return favor of posting a follow-up message saying how you fare. Good luck, and thanks for the visit.
