Sustain pedal not working on my Yamaha P-90

When I turn on the keyboard and press a key, it is already sustained. When I plug in the sustain pedal, all keys stop sustaining and the pedal stops working.
Sometimes, it is in reverse. The keyboard gets turned on, and the keys are not sustained. I plug in the sustain pedal and everything is sustained. Stepping on the pedal does nothing.
I suspect it's not the problem with the pedal, but I'm not sure. My keyboard also has a problem of sometimes cutting off power, so I think it has to do with circuits.

What I figured out is that when i turn on the keyboard, if i hold down the pedal by accident, it will work in reverse. I dont know if this is what you mean. If it is, just dont touch the pedal when you turn it on. If it isn't, try to return the pedal. I dropped one, it had this problem, and they gave me a new one. Your cord for it might have been bent (?). Also, turn the keyboard on with the pedal already plugged in. It's not made to be plugged in while it's on. Hope this helps. - Matthew

I had the exact same problem with my Casio keyboard and a Yamaha sustain pedal I bought.

I'm not an electrical genius, but I was able to get it to work by opening it up and doing a little modification. Of course I first just tried switching the white wire with the black one but that didn't change anything at all when I tried it. It turns out the Casio wants the circuit completed to sustain, and broken for no sustain, which is the opposite of what the Yamaha pedal does.

I opened it up and mine had three three flat metal strips let's call them Top, Middle and Bottom. The Middle and Bottom ones were joined together on the right side, and the Middle and Top ones were touching on the left side when the pedal was not pressed. These seperated when the pedal was pressed, thereby breaking the circuit because the wires were on the top plate and on the joined Middle/Bottom plate.

So to flip it I:
1. Unsoldered the Bottom wire
2. Cut apart the Bottom and Middle plates on the right.
3. Bent the Middle plate on the right to touch the Top plate instead and soldered those together.
4. Soldered the Bottom wire back on.

That's it! Once I figured it out, it took only a few minutes to fix.
Good luck!
Paul

    Paulll, you didn't read melsaboo's post at all, it has nothing to do with polarity (which you inversed by twikling the switch), post says sustain goes on and off by plugging / unplugging the pedal ( I got the same problem). Your good with wires but can't read very well

SOURCE: sustain is in reverse yamaha p-85

Make sure the pedal is plugged in before you turn the keyboard on and do not compress the pedal until the keyboard is on. Good luck.

every sustain pedal got different polarity.. normally just go to global setting on your keyboard and change damper polarity setting to plus or minus (select which one work with your sustain padle).

Hello- my P95 sustain pedal does not work when plugged in but the sustain works when you disconnect the cord from the back of the keyborad


This is confusing... you say "the sustain works when you disconnect the cord"? How can that happen? and doesn't work when it is plugged in.

MOST sustain pedal problems are due to people using a different pedal than the keyboard is designed to use. It is very common that someone tries to use a Roland sustain pedal on a Yamaha and oof course it doesn't work because the Roland pedal is normally closed and Yamaha usually requires a normally open contact.

A FEW keyboards now check the state of the pedal input when power is first turned on and configure the pedal polarity accordingly. For these keyboards, make sure the pedal is plugged in before power is turned on.

A bought an Yamaha DGX 640 grand a week before and the note sustain for a longer duration and overlaps with the current playing notes. I checked the sustain in the function setting and it is also showing ...


The function setting is for the PANEL sustain (Page 68 of your manual)

The other method of sustain is by footswitch or pedal option. See page 13.

If you use a footswitch, it needs to be a normally open contact type. If you plug a Roland type in, it is opposite polarity and will sustain UNLESS the pedal is pressed. Make sure nothing else is plugged in the sustain jack... headphones that are inadvertently plugged in there would sustain.

Hi. I'm Using PX330 as a midi controller that plays "Galaxy pianos" in cubase 5. I'm interested in buying a continuous sustain pedal (the one I got with the piano is an On\Off pedal). can you...


The Yamaha FC-3 uses a TRS (three conductor plug). The PX330 does NOT use TRS jacks for the sustain and sostenuto pedals so they are NOT compatible with the Yamaha FC-3. Therefore I would conclude that continous sustain that the Yamaha pedal would be used for is NOT supported.

Is a sustain foot pedal similar to a tattoo machine pedal?


The sustain pedals have only two wires. Usually they terminate in a 1/4 inch mono plug.

yamaha USUALLY sustains when switch is closed. Roland usually sustains on a switch between the wires when the switch is open.

NO POWER should be supplied BY the sustain pedal... it is ONLY a switch.

I want to plug in a sustain pedal to my very old yamaha psr 300 keyboard but there isnt a slot. the only slot it fits into is the headphone slot, but then you get no sound! can I get an adaptor for this?


Sorry to bring the bad news but the PSR300 does NOT have a connection for a sustain pedal.

It will however recognize a MIDI command for sustain so if you had a MIDI sustain pedal that emitted controller 64 code, you could use that.

It is UNLIKELY you would want to do this as such devices are not readily availablle. If you slaved this from another synth that had a sustain pedla capabilty you could play booth together and use the sustain of the other synth.

Sustain Pedal Opposite Effect


I found that if I plug in the sustain pedal BEFORE turning the power on, it works fine. If I plug in the sustain pedal AFTER turning the power on, then it works in the opposite way. Probably just the design. So I would try playing with that before doing anything drastic.
