I noticed the following problem:
I use my BB with a Boomerang III. There are songs in my set where I want to use the BB (and the Rang), and there are some where I just use the Rang alone. When I just use the Boomerang without turning on the BB, it still sends a MIDI sync to the Rang, even though I’m in a completely different tempo (there’s no song being played by the BB, ergo it stays on the tempo of the last or next song, depending on where I am in the setlist). Ergo: the Rang cuts off my loop because it syncs to the wrong tempo.
This is really urgent to me - I can’t play that song without unhooking the MIDI connection between the two devices.
