The sustain pedal works in reverse

by David Cantrell
(lula Ga)

When I press down on the sustain pedal, it mutes the sound. It does the opposite that I am used too. How do I reverse this to where you press down in the pedal ---- it will sustain???

Your Pedal polarity don't match with your Keyboard.
by: Mario

What you need to do is to change the polarity of your pedal. Maybe there is a swicht on your pedal or on your Keyboard input. Pedals never go wrong the problem is that not each pedal work with every Keyboard-Piano. The solution ? Try to change the polarity, that's a matter of cabling and soldering when there is not a switch on board.

The sustain pedal works in reverse - Fix
by: Andy

I also had this problem when I first set up the piano. I discovered that i had the piano powered up when I initially plugged in the cord for the pedals. All I did was turn the piano off, unplugged the pedal cord, waited a few minutes, plugged the pedal cord back in again, then powered up the piano. Problem solved!

We have tried this several times and it is not working for us either. 35 years of playing and yamaha never lets you down with simple tasks undone.

How to fix backward sustain pedal
by: Paul

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.
3. Bent the Middle plate 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!

How to change polarity without a switch
by: Yamaha pedals always break

After working with Yamaha pedals for many years and throwing away about 10 of them, I've found that you can simply change the polarity by holding the pedal down while plugging it in to the back of your keyboard. This has worked for me before and corrected the problem.

Yahama pedal in Casio CDP 200
by: Sangma

Using the sustain pedal of Yahama in Casio CDP200R, will it spoil the keyboard? The sustain pedal of yahama works reverse in Casio, but I'm going to change the polarity. So doing it, will affect in any way to the keyboard?

Buy a dual polarity sustain pedal NEW
by: Jay

Different manufacturers make different sustain pedals and some have positive polarity and others have negative. Buy the sustain pedal that is supported for your device or buy a dual polarity sustain pedal so that you can switch the polarity on different devices.
