Tom, I physically re-configured a Technics FC2 Technote 4 pedal unit by installing four individual outputs 1/4" jacks on the back of the box to accept standard 1/4" mono cables. I then assigned Tyros foot pedal 1 to sustain, pedal 2 to vocal harmony on/off, and pedal 3 to fill self and plugged the sustain cable to the far right foot controller pedal, the vocal harmony cable to the far left pedal, and the fill self cable to the pedal right next the far right (sustain) pedal. The other pedal on the four pedal controler I leave inoperable (unassigned). Hope this was the answer you were looking for. - Scott
