Brock,

Thanks for the quick and thorough reply!

Correct me if I am wrong but if I use pitch A for pitch bend down and Pitch B for pitch bend up then I would also need to set up those same controllers to instantly change the pitch mix respectively to 100% for pitch A or Pitch B.  Otherwise I would hear some of the original pitch mixed in.  

Alternatively I could use Pitch A only mixed at 100% and then experiment with MIDI values that will result in the appropriate bend.  OR could I set the max value at +2 1/2 steps and min value at -2 1/2 steps and then set up one foot controller from MIDI value 64-0 and one for 64-127?  
Which would be better or are they essentially the same?

Thanks in advance for the help
