Here's something that annoys me:
If I have an expression pedal connected (I do) then I can chose in the PERF tab of the PROGR not have it connected to anything.
If I have a footswitch connected (I do) then I can't make that same choice - the footswitch always has to do something. That means that if I have a multi where I want to use the footswitch to control sustain on one slot, but do nothing in the other slots, then I have to set the footswitch to do something ineffectual on the other slots, like turn an unused effect on/off. This is a pain, why can't I just disable the footswitch completely if I want to, have another option, "off"?
Or can I? And I've just missed where this setting is...?
