I have 2 expression pedal, both of which work, until I change a patch. exp2 then stops working until I reboot the HX. It has to be a firmware issue, since if I swap the pedals, they both continue to work on exp1 ;(
Are there any bank-specific settings? I'm assuming the pedal 2 assignment of exp/amp are global...
Resetting seems to cure the problem, but as soon as I restore from my backup, it's back again.
It's seriously frustrating!
