Our church organist had the same problem with the pedal to the electronic keyboard. One of the guys in our choir took a 1/4" piece of plywood, cut it into the shape of a foot, stained it, glued rubberized shelf paper on the back, placed the foot control on the 'barefoot' cutout, placed trim around it in an upside down "U" shape, slid the foot pedal into it and it worked like a charm.
