Thanks for in depth informations. I will reread it later, as I'm new to both programs.

At the moment I want to use RB, because it can integrate with BB in a way so I can have both realtracks and the chords in RB. Therefore I don't export a file from BB, but open the SGU file in RB.

After some experiments based on your writings, I have realised, that the BB master volume have no effect in RB this way, but I get more volume if I turn the tracks all the way up in BB.
