The Mac is running on an old Win PC i3 3.2GHz 4GIG Ram,
the Win PC's are i5 3.3-3.5GHz 8GIG Ram.
As I said it should be instant if it's playing from RAM.
When ReWire is implemented and BB is a slave, you press play on your DAW there should be no delay start, you want it to follow the DAW instantly, but it's going through some routine, that needs to be bypassed and like just play already ZZZZZZZ.
"Generating arrangement... please wait" no sorry, what arrangement ?
So I think that is going to have to be fixed.
