I'm having the same kind of problem here
I use extensively EXP2 for volume pedal and EXP1 for wah, use exp_toe to bypass both
and save alla my patches with volume pedal activated and wha bypassed.
- with 2.71, patches would always load with EXP2 activated :
I could end a solo with wah activated, then switch to rhythmic preset, and I used to consistently get control of the volume pedal.
- with 2.80, patches load with whatever EXP precedently activated:
so when I end a solo with wah activated, then switch to rhythmic preset, I get to have control of the wah while it's bypassed,
while volume pedal is active but not controlled. If I press exp_toe the wha activates but it's not controlled anymore, while volume pedal is controlled but bypassed.
I think I'll look for a workaround like using a footswitch instead of exp_toe and tweak exp mappings, or rollback to 2.71, while waiting for 2.81.
Is it confirmed that Line6 knows about this bug?
