Question about Yamaha Music
Originally, the problem was that the pedals would not work unless the plug was duct taped into the unit...and then only sporadically. We opened it up and discovered a crack in the circuit board....probably from continually contorting the plug to make the thing work. So, we repaired the circuit board and tested it with a voltage meter....checked out. Now, this piano sustains continually as if the damper was held down. I like to put the soft pedal in break/fill mode.....and it too, continually breaks/fills as if it was held down too.

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

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.

Testimonial: "I really am touched by your response, thanx a lot"
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.

First thing is to check the connector is fully seated... sometimes most of the contacts make but one might not. Beyond that, contacts in the pedal are next suspect.

It sounds like the inputs from the pedal switches are "floating", that is, not pulled up or down and they are drifting across the logic threshold. If I could find a schematic I could direct you right to the problem. For now, check the voltage across the switch contacts with a high impedance meter. Also check the resistance to ground of the common of the contacts. Without a schematic I am afraid to have you try things lest I direct you to do something that would cause damage.
