sustain pedal doesn't work

by Steve
(Simi Valley, CA)

Sustain doesn't seem to work. I plug in the pedal and it won't sustain. I unplug it and plug it back in and it won't stop sustaining. The pedal doesn't respond. I've tried both ways, with the pedal sustaining while pressed and not pressed (switch on the bottom) but it doesn't seem to make any difference. I've tried other pedals and they do the same thing. I've tried turning half damper on and off to no avail. Also, a reset to factory defaults does nothing as well.

DGX-640 Sustain is WEAK!
by: Larry S.

I've had the YPG 625 and 635. Both instruments have perfectly fine pedal sustain. My DGX has extremely minimal sustain... its ridiculous actually. I've been thru every possible setting/adjustment and been thru the manual. I've tried THREE different pedals that all work fine with 2 different YPG-625's and a 635! It's difficult to believe the piano itself is faulty. ANY IDEAS???

sustain pedal working in reverse
by: Dom E

I have a Yamaha MO8.
I had this issue and the turn off , unplug pedal ,wait a minute or 2 , plug pedal in and turn on keyboard did not work.
What did work was turn off, unplug pedal, wait,plug pedal back in but keep pedal depressed while turning on the keyboard. Good luck.

How do you switch the polarity inside the pedal when there is no switch?

Actually, the pedal has a switch on the bottom that allows you to change the polarity. I ended up taking it to a repair shop and a new pedal worked! The two pedals I tried were both broken. Turns out the pedals are very fragile and the wires in the cord can get disconnected. A new pedal did the trick. I have a S90ES. I guess the keyboard is perfectly fine, it's the pedal that was the culprit. For me, it was coincidental, I suppose, that both pedals I tried were faulty.

You don't say which keyboard you have, but some of them work on reverse mode. In other words you have to go into the utility set up and reverse the polarity of the sustain pedal. I had to do that with my previous yamaha keyboard.

Tyr plugging in the sustain pedal with the power off. Never plug it in with the power on.
