Almost, but not quite.
As I understood, the mobile version as it stands is more like a remote item or mp4 player or even extension to PC version.

I am talking about more what you mentioned:
"Your bass player and drummer don't show up at the gig because the drummer ran off with the bass player's wife"

In the scenario I described (if you export all tracks as waves/mp3s in one compressed file and let the android app open and sort these properly on mixer with solos and mutes at your disposal) You can use it as backing unit soloing or muting tracks on the fly as needed. (If bass and drum players are fighting outside for example) Basically, a condensed multi track player... without the need of PC once you load your compressed files of course.

Oh yes, programming solo/mute buttons to be used with bluetooth pedal would also be a plus.
