I can confirm almost every issue that Petja describes.
It is really not neccessary to describe which the whole thing because the H8000FW Misbehavior is so obvious! Chose whatever pedal or footswitch and assign it to whatever parameter, then chose another pedal or footswitch and assign it to whatever.
Alternatively go through what Petja says. If in doubt , make assumptions. You don't need to ask Petja for details.
It's really obvious ! It is apparent !
