1)  i am running 4.8

2) check

3) i'm using an Ernie Ball VP Jr.  which is a volume pedal by description.  when i sweep it, it DOES go from 0-100, but only on the pedal.  if i monitor the effect on my iphone it sweeps within my set predefined range.  that said, i'm not having issues with the expression pedal.  my problem is with my tap temp button not functioning.  can the volume/expression pedal still be responsible?
