On the subject of foot pedals, I have used a Y****A expression pedal for many years and through many Technics keyboards. However, the polarity is originally opposite to Technics, so I had to open up the pedal (no mean task!) and swap wires over. That done, the Y****A pedal is much superior to the plasticky Technics one (and it has ample room for my Size Tens!)
