I had to switch the Aero back to slave sync because I can’t record new 1st loop in a new song because Aeros stops midi sync when it goes into record mode, really annoying (sync “always on” check). And in a new part too.
I tried everything and everything is configured well. In play mode everything is fine.
I also have a very slight desyncro between the Aeros master and the BB which I do not have between the BB master and the Aeros
