DNJ, you were not forced to covert, right? If so, that ain't a true conversion.

Kidding aside, when I play the digital piano, all I need is a sustain pedal. Now that I am getting a Numa Compact 2x with drawbars, I'll use an expression pedal. Also, I use a MIDI foot controller to send sysEx to my Ketron SD40 to call up functions and sound patches. Korg arrangers have a very good MIDI implementation. You don't need their dedicated foot pedal, but any midi foot controller can send midi program change messages to call up functions.
