Just installed the firmware. No problems.
Ability to "backtrack" (even though "limited' to recalling the previous preset), per preset or global, is awesome.
Showing names when pressing IAs is awesome.
Ability to switch off all IAs in a "linked" group is awesome.
Manual update is awesome.
I think the update is, eh, awesome!!
Ability to select alt.presets, plus X/Y and the capacity for 2 amps allow amazing flexibility now.
Suggestion:
How about adding the capability to choose between X and Y by pressing and holding the IA for a second or so? I realize this would raise an issue with the LED state.
Alt: add a 'generic' IA-switch (CC) for X/Y switching. Pressing and holding any effect IA will 'select' that effect, and the generic X/Y switch switches between X and Y.
Or even better: adding a single IA set to 'generic X/Y' would suffice. Press it once to get into Select mode, then press an effect IA to switch between its X and Y state.
No more need for a separate X/Y-switch for each X/Y-enabled effect.
Okay, I'm getting carried away.
