A second go at a multiplayer mechanism. On the top left, you see four iPhones in the group. On each iPhone, there is a “GroupLoops drop zone” into which you can drag the loop you have finished building. When you have done so, it appears on everyone else’s “drop zone,” and it gets added to the song and played back in real time. Each member can freely drop their loops into the zone, and also remove anybody else’s loops - whether they be melody, rhythm, or harmony loops.
