My Williams Allegro 88 keyboard sustain pedal is doing the opposite of sustaining. I lost the manual so I also don't know how to reset it and if this will fix the problem.

Assuming this has worked in the past (otherwise if you have changed to different pedal that is the problem) the usual thing is the machine samples the state of the pedal at power up and assumes the polarity of the pedal is at rest. Make sure you are not pressing it as you power up. Also verify the pedal is COMPLETELY plugged in... sometimes they are not quite fully in and that causes a problem, especially with the two stage versions that are sometimes used.

    My Williams Allegro sustain pedal is terribly difficult to work with. Sometimes it sustains when pressed, and sometimes it just plain doesn't! Is it me, or is this pedal just a piece of junk?? I do love this piano; no problems there, it's just that the sustain pedal that came with the keyboard isn't functioning the way a sustain pedal should. Does anyone know if there is another manufacturer's pedal that will fit this particular Williams piano model? After having read up on it, I don't think it's me. The pedal is plugged in properly, and I've been playing piano for almost 50 years (electric pianos for about 20 years) so I know how it SHOULD work. The piano was a gift, but if I had gone out shopping for a digital 88-key myself I probably wouldn't have bought this one based on the complaints about this dang pedal. Any ideas or recommendations??? Thanks!

    I found an easy solution, with just a wrench and pliers: I took the pedal apart (it's held together with just one nut and a bolt which acts as the axle). The circuit is caveman simple - the pedal simply pushes one piece of bare wire into contact with another piece of wire. I bent the top wire (the one with a free end - you'll see it) so that it lies a little bit closer to the other wire when the pedal isn't being pressed (without actually touching). That way when you do press it the wire is more likely to make contact. I put it all back together (there were some little washers that were awkward, and the spring isn't held in with anything which is also awkward. This thing was certainly built on the cheap). Now it works way better - it always sustains when I push it.

    Note: I actually bent the wire twice - I bent it downwards near the middle of the wire to bring it closer to the other wire, and I bent it upwards near the free end to bring it closer to the pedal. A bit of a zig-zag. The upward bend ensures that it will come into contact with the pedal when you push with your foot.

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).

Fc4 sustain pedal is in "sustain" mode at all times -- it won't release the sustained notes. I tried plugging the pedal in (to a roland ep-9) before powering up and had the same problem.

Sorry, but the Yamaha pedal has the opposite sense (it is a normally open contact) than what is REQUIRED by Roland equipment. Roland requires a Normally Closed contact. Unfortunately, one is confused because the Roland jack for the sustain shorts itself to no sustain when you unplug a pedal. SOMETIMES one can open a pedal and with soldering iron change a wire to reverse the pedal sense IF the particular pedal has both contacts available.

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.

The answer is NO... Roland uses the opposite sense switches on foot pedals... They use NIRMALLY CLOSED and your Yamaha is a NORMALLY OPEN switch.

SOMETIMES you can open these pedals and find that the pedal has the opposite sense switch available and you only have to unsolder and move one wire to make it a NORMALLY CLOSED pedal.

Ensoniq KT-88 - sustain pedal works opposite the way it should

Usually that indicates that the polarity of the jack for the sustain pedal has been switched or someone has substituted another pedal with the wrong polarity. Try looking in the manual to see if that is an editable parameter for people who might not be able to obtain an original pedal. You may have to initialize the keyboard which is on page viii of the manual. The jacks on the back for footswitches are on page 1 and 2. The footswitch settings are on page 9. I found the manual here: I don't know if you have the single footswitch or the optional stereo footswitch. If it is the single footswitch, the default setting should work correctly if it is the original SW-2 or SW-6 pedal switches. If it is the optional SW-10, the FTswL setting should be Unused. Hope this helps.

Sustain pedal not working on my Yamaha P-90

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

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.
