On the current FW 3.11.1 my exp pedal while heel down does read 0% but can flicker to 100% and back quckly which activates and Wah on my HX Stomp momentarily. Have re-calibrated many times and altered sensitivity and it can be steady for a while but then goes off again.
If I drop back to previous FW 3.10.2 I have no issues. I only have one exp pedal but have tried different cables. Pedal is a DOD mini expression pedal set to TRS mode.
As I say previous FW there are no issues.

Can you try this firmware and let me know if the issue still persists for you? Seems like there is a setting we need to add to suit different exp pedals.
Many thanks for such a quick response. I’ve updated with this patch and it seems to be back to how it was, so looks like you’ve fixed it
Thank you, Nick
Hey there, rehashing this old thread. I am having the same issue with my MC3, but I wasn’t able to find any firmware fix for it. Is there something I can do aside from downgrading the firmware? Thanks!
James sent me a patch. Probably create this as a new issue and James will reply.
I had the same problem, tested the firmware update, seems to have fixed it. Thanks!
FYI it was working fine when using just one CC message over EXP 1.
But I was testing sending 4 pitchbend messages over EXP 1 to control a GM-800 when I ran into this problem.
