Hey Vic,
I've been a GeneralMusic keyboard player for sometime now (Bachman, WX2, WK4, and now WK8).  I still have the 3-switch foot pedals I got with my Bachman and have used them on all keyboards mentioned above.  They are the small, square shaped pedals, 3-in-a-row style.  I have the volume (expression) pedal somewhere but haven't used that in quite some time.  The 3-pedal setup works great.  For the most part, I have them programmed for one variation back, one variation forward, and fill.  But switching between Harmony or Rotary S/F is truely helpful.  I guess it just depends on what song you're playing.  Granted, the pedals are a little small, in other words, I have stepped on 2 pedals at once (big feet?) but I've gotten use to it over the years (read, practice).  At home, I always play with my shoes off, no problems then.  If it was me designing them, I would have made them into the shape of regular piano pedals.  I'm sure you can find those type somewhere??  Hope this helps.
