Hello, After reading these questions and answers, I'm left with another question regarding this matter. Ik own a Pod Pro X HD and FBV shortboard (mk-1) and a Roland EV-5 exp. pedal. For some reason the polarity of this exp pedal is reversed, I think. I just can't get it to work using the pc editor. Tried tweaking the controls but it still doesn't fully work. Any tips or advice? (other than buying a Line6 exp pedal, I'll keep using my trusted old gear for a while, like Nucleus X said ;) )
