Which outlet on the back of my Yamaha P-95 piano should l use to connect to an amp? My options are headphones, MIDl in and out and pedal unit and sustain

SOURCE: 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

There are two types of damper pedal switches, on that is closed until you press it, and one that closes when your press it. It sounds like your Casio is expecting one type and your Roland pedal is the other type. A quick way to test this is to plug a guitar cable into the Casio pedal input and see if the keyboard sustains. If it does, then your Casio requires an "normally closed" switch.

Some pedals have a small switch near the cord or even on the bottom of the pedal that will reverse the switching operation (BOSS pedals, a division of Roland, have this feature). If you can find that, then change the switch position and you should be OK.

If not, and you feel like digging into your pedal, you could take the bottom off of the pedal and check out the switch itself. Many pedals use a switch that can be used either way. The clue will be on the switch itself. If there is an extra tab on the switch that is unused, then switch the wire that is furthest away from that tab to that tab. This will probably involve soldering, but it is nearly impossible to damage anything.
If moving the wire that is furthest away does not do anything, then try putting that wire back and switching the other one.

If your pedal does NOT have an extra tab, you're SOL, unless you want to buy a replacement switch (unsure of make). If this is the case, you are probably better off getting a different damper pedal - preferably one that is marketed as "universal"

SOURCE: The sustain is on all the time.

The pedal activates a microswitch fitted to the circuit board. I suspect for some reason unbeknown to man and spirits this switch has become "stuck" or collapsed. If the latter then it has to be replaced as they are soldered to the board. You coulod open the unit trace the pedal back to the sustain switch and "jiggle" it manually to try and release it. A small amount of WD40 on your finger and rubbed over the pole of the switch( do not spray it) should help it to stay releaased until wanted. If you see corrosion on the board near the switch then take it to a music repair shop as this corrosion is like a cancer and will spread to other keys.Mice piddle is not unusual on keyboards and a great destroyer.

SOURCE: Sustain pedal on Yamaha DGX not working

Hi, I had the same problem, but I have an easy solution. I am trying to connect an FC5 to a Casio CTK-3000. The problem is open vs closed circuit in the pedal and the way that the casio interprets the info. Paulll's fix is correct, but you do not have to use soldering. Simply remove the cover, unscrew the silver screw, and you will notice that the black contraption that holds the two metal strips has one side that pops off. Pop off this side.
Now, notice that the short strip is on top and the long strip is on the bottom. The way the strips bend mean that the circuit is closed when there is no pressure on the pedal. When you press the pedal, the white knob on the long strip pushes the long strip down and breaks the connection with the short strip.
What you need to do now is remove the two strips and slide them back into the black contraption with the long strip on top and the short strip on the bottom. The white knob on the long strip should be facing up. Make sure when you do this that you hook the short strip over that little horizontal black plastic rod so that it will easily contact the long strip when the long strip is pressed down.
By bending the top (long) strip a little, you can make it so that the long strip does not touch the bottom (short) strip in the relaxed position. Make sure that the ends of the strips where the wires join do not touch each other either. You now have an open circuit in the relaxed position, which is what Casio recognizes as NO PEDAL.
Pop the side piece back on the black contraption and screw the black contraption back in place with the silver screw. Set the spring back in place and reattach the 'pedal'. Make sure that there is enough clearance between the top of the white knob and the inside of the pedal so that the circuit remains open in the relaxed position.
Now, if the two strips are NOT touching each other, when you plug it into your Casio, the Casio will not recognize the pedal, which is good. When you push on the pedal, you will close the circuit and the Casio will recognize the pedal.
If you push on the pedal and nothing happens, then the two strips are not contacting each other in the fully pressed position. Take the unit apart and try again.
If the Casio still recognizes the pedal even though you are not pushing on it, then the two strips are contacting each other at any place along their length. Take the unit apart and try again.
Enjoy your new working pedal!

PS. If you Casio won't work with your computer, there is a fix out there for that too. It involves removing (or renaming) some files that Logitech loads on to your computer when you install a webcam. Weird, but true.

SOURCE: Can I replace the pedal unit to the Yamaha Clavinova CVP-75?

I can't solve the problem, but just wanted to sympathize because I have the same problem. My pedal is broken on my Yamaha Clavinova cvp85a. It worked wonderfully for years but finally it broke.
I'd be in the market for buying a new pedal or fixing the old one. But I've not found any suggestions in any of these forums for either solution.
