Background: I had already purchased a Roland DP-10 Half-Damper pedal and wanted to use it with Yamaha synths. I didn't need to use it on a Roland anymore so I've decided to simply rewire the internals to make the Roland pedal match the Yamaha FC3 (or FC3A). After analyzing the wiring on the Roland and Yamaha FC-3 half damper pedals, I modified the Roland pedal as described below. Note that both Roland and Yamaha half-damper pedals use a similar potentiometer (~10k-ohms). So AFAIK, there's no real risk damaging the internals of the Yamaha synths. In any case, do this at your own risk . Preparation: To open the pedal, use a screwdriver and remove all the screws. Pull out the circuit board: Modification: Take note of the wiring before the modification: White (Tip) Black (Sleeve) Red (Ring) With a soldering iron, rewire as follows: Red (Ring) White (Tip) Black (Sleeve) Represented logically: Testing: To be sure I rewired and reassembled th...
