That's a pity... it'd be super useful for me. I use the PG live, and I love snapshots for the gapless tone changes, but I have two issues:
1) the inability to change from clean to dirty using snapshots, which I've kinda solved by turning off the amp, changing the IR and adding a minotaur and some eq to create a nice clean tone. It would be much easier if an amp had a "channel switch" or if the drive went from clean to distorted, but none of the amps has either. But it's fine, I managed to get a clean sound anyway.
2) I have to use a few presets to play all songs. One preset covers most songs (4 most common snapshots). If I had 6 snapshots I'd only need one preset, or maybe two to cover all my needs, but I'm using 5 presets to be able to play all songs using snapshots.
But thanks for the reply anyway! I've been using line 6 modelers since 2003 onstage (first a pod xt bean with a midi controller, then a pod x3 live, a pod hd500 and now the pod go).
ps.: Just found out something else I'd find useful: being able to move snapshots around. Replacing snapshot 1 with 3, for instance. I have a preset ready but found out that the "lead" snapshot would be better placed next to "rhythm" (instead of the upper row buttons), but I can't just move it.
