Patches and discussion for Ensoniq VFX family

Hello, I wnted to ask if in some way is possble to have the same patch 
effects
with a pedal switch inssted of using patch select button. I find quite 
uncomfortable those 2 buttons
while playing the keyboard, and I am searching an alternative method to 
trigger the button functions.
Is it possible with a pedal and if so how ?
thank you

Rick
