I have a Casio CDP-120, which only supports one pedal. Since I now have Pianoteq, I'll be playing through my computer, and the possibility struck me of a triple pedal that would input to my computer via MIDI. Does anyone know of such a thing?
Can't guarantee such a thing exists. One existed once : http://www.forum-pianoteq.com/viewtopic.php?id=2160
If you want to spend the money, and have 2-3 USB ports (or a hub):
Roland RPU-3 + 2-3 Midi Expression Interfaces

The RPU-3 will give you continuous control.
