My Casio Privia PX-110 Damper Pedal Hack

As i mentioned in my previous post, the Casio Privia PX-110 Digital piano features a strange damper pedal that seems to have reverse polarity when using anything but their included footswitch. This is clearly an attempt to push a proprietary 3-pedal accessory by Casio (the SP-30) - more annoying than helpful, given that the SP-30 effectively anchors an otherwise svelte and portable instrument.

Thanks to John Lat's comment, it turns out that the workaround to adapt a standard damper pedal for the Privia is a lot simpler than i had anticipated, although it does involve some brutal surgery if you take my approach.

I started by opening up the casing for my M-Gear damper pedal to study the wiring. My first thought was to try to find some solder points to reverse the wiring, but given the cramped quarters and my lack of soldering experience, i decided to do the simple wire cut instead. With a handy wire cutter and stripper, i was able to take off the outer black rubber insulation and expose the two wire leads within:

Cutting the wire was the scary part - until i saw how simple the connections were!

Stripping off the insulation from the inside wires was tricky - you need to use a very gentle touch to start the incision, being careful not to cut into the inner wire. Once that was done, all you have to do is re-attach the wires connecting red to white, then white to red (or whatever opposing colors your pedal presents):

Twist together red to white, then white to red

Once that's done, a little electrical tape helps insulate the exposed wired:

All taped up and ready to pedal!

And there you have it! Keep in mind, the pedal needs to be set to "switch" mode to work properly - if it's set to "continuous", you'll get the same reverse polarity problems you started with before the hack. Even though you don't get advanced pedal techniques enabled with this hack, at least you can get the "on/off" damper pedal effect with the proper foot orientation.

How does this work? I think the pedals just have a open or closed circuit, right? How does this hack change that? The circuit will still be open or closed when the pedal is depressed, reversing these wires won't have anything to do with it, or?

There's a polarity reversal switch on the bottom of that pedal... ;)
