I have noticed when using the WAHWAH setting and using a MIDI CC for the values, it works, but the response is super slow. It's unusable as a wah. I had replaced my WAH pedal with the ModFactor. I cannot work out why this is so slow. The range of values goes from 0 – 100 but I can rock the expression pedal back and forth and it will stay on 100.

Any ideas?
