I am on the latest firmware version and I am experiencing strange behavior too. I have an Ernie Ball Jr 25k connected to my MIDI controller. The Ped -> C20 and I am broadcasting MIDI changes but the ModFactor is responding slowly and not accurately. I have calibrated the Exp Pedal with the MIDI Controller. 90% of the pedal sweep gives values 0-16 and then the last 1/4" gives massive jumps. The lag is slow and pretty much unusable. Has anyone been able to use the ModFactor as a Wah with a MIDI Expression Pedal instead of attaching directly. As I have 3 Factors I don't want to have 3 exp pedals on my board!
