Just to add a bit to Peter's answer, Biab regenerates the tracks every time you hit play unless you tell it not to. You're question implies you think this is some kind of problem but it's actually by design. A real band will not play the same tune exactly the same way twice. Similar yes, but not exactly the same. That's one of the neat things about the program, it gives you some variation to play along with just like real band members will.
