Well, that was like brain surgery should be:
Boring, in a good way.
No multicore, more audience space, move around to see what the guitars are playing…
Put a couple of elastic bands across the back, from one corner to the other, of the iPad as a cheap grip.
Android tablet with set list…
In ~6 hours I had two <.5 second connection glitches, both in the same place in the room.
Qu-You was used by 3 musicians (on in ears) – mostly during soundcheck/rehearsal.
Many interested parties…
