I recently purchased a 2nd hand Casio WK 1630 keyboard. I have a Yamaha sustain pedal which now works with the Casio, but oppositely... i.e. sustain is on when the pedal is not depressed and is off when it is depressed. I'm told there is a way to change the pedal polarity on the Casio so the Yamaha pedal works as it should with the Casio. Can anyone tell me how to do that. I have found nothing in the user manual addressing that subject.

BTW... just joined... looking like a great forum!!!

If there's nothing mentioned in the Casio's owner's manual, I suspect it isn't possible to change the polarity.

Cheers,
James

Sometimes you can change the polarity by depressing the pedal at the same time you power on the keyboard. Worth a try....?

Some pedals have a little polarity switch on the bottom, so I would take a look there first.

As a last resort, if you can't find a switch and can't find any way to switch the polarity setting on the keyboard itself and you're handy with stripping a few wires it's relatively easy to switch around. If you slice the wire going from the pedal to the keyboard there should be two signal wires inside (there is also probably a ground wire in there). You could just just cut the two signal wires and splice them to the opposite color.

I've done it just once and seemed to work without any problems. I would only try this if you are a little handy with electronics and can afford to ruin the pedal if it goes bad though!

Congrats on the first post BTW!!!

Tried that TBrown... The pedal had only one wire wrapped with a shield wire, I reversed those and while the pedal still worked, it did not work any differently... same sustain when the pedal was not depressed.

still looking for a solution...

I'm not sure this will work. In the pedals I have used, the pedal activates a switch that, when depressed, either closes the electrical connection between the two wires or opens the l?connection. Simply reversing the two wires would not work if you have one of these. Instead, you would find the switch inside the pedal and disconnect one of the two wires from one of the two You can figure out which wire to move with an ohmmeter (or voltmeter) by determining which contact closes and which contact opens when you depress the pedal. You will probably need to solder the wire.

Can you post a picture of the inside of the pedal?

Hmm, I see. The pedal I was working on had a ground/common wire, so the other two wires must have been a normally open and a normally closed one, so switching these would make a difference. If there are only two wires, then switching them wouldn't do anything, as you've found out.

After a little searching about Yamaha sustain pedals, have a look at a post here by Paul , about halfway down the page. The OP seems to have the exact problem you are having and this fix seemed to work, although it does require some soldering.
