I use a 4 way foot controler in conjuction with an expression pedal and yamaha foot switch, the only diffulculty I have found is the instabiliy of these switches.My answer was to set my keyboard stand on a seperate solid wooden base,I then played around with the placement of the switchies untill a natural position was found the switchies were then secured in that position by a small framework for each switch and now I have no proplem hitting the right switch. My set up is 1. fill 1 2.panel inc 3. panel dec 4. fill 2 the seperate foot switch I use for rythm end.
