The RB regenerates song always when MGU or SGU file is onpened in RB.

I listened drummer alone. However, it seems more that drummer is doing his job in slowing down the tempo a few bars earlier, but... other realband players do not pay attention to it. In my example drummer also has difficulties in knowing when song actually ends.

Only solution is to use only one tempo within RB and Real Tracks.

By the way you can get all sorts of interesting examples with my scenario. It is not time to say I cannot reporduce the case . It works in every case.

Thank you for your time
