Hi. As an aside to this, I've got an issue where I have an external expression pedal plugged into EXP2 on my HD500. EXP2 is assigned to Volume with EXP1 assigned to a Wah. Sometimes I am able to use both with the same patch, other times only one of them works. I can see the "pot" changing position in Edit on my PC, but the sound doesn't change. I have done a global reset after saving my bundle, no change, so I'm thinking of reinstalling the firmware using Monkey.
Any Ideas?
