as GroupTheLoop can get synced over Ableton Link, I wonder if the following would work:
..... 2 musiciens, each one with his own Ipad running GroupTheLoop
.....Ableton Link activated so that both apps run at the same tempo
.....one of both musiciens triggers the changes of track groups per MIDI, on both 2 Ipads at the same time
This would enable the 2 musicians to loop together on the same song structure, with a high degree of freedom.
Could that work technically?
