After a only one session with the PF:
I'd like to see the AUX SW functions respond to button RELEASE to restore the MIN value, in other words, have a non-latching function.
I'd like to have AUX SW parm assignments stored with a patch. They'd be infinitely more useful.
I'd like to be able to map the function of at least one (the middle) on-board button switch as can be done with the AUX SW settings. I'd be able to leave my AUX SWITCH at home.
I'd like the diatonic tracking to be more solid. I was surprised to hear a generated note switch down/up a scale step in response to a single sustained note when a little vibrato was added. This only seems to happen on a few notes (and the guitar was in tune and decently intonated).
