I think register jumping is the primary reason someone might complain about the bass line constructed by BIAB.

When you stitch together snippets of audio of varying lengths, how can the program know that the bass line ended on a low pitch, but the next snippet has the bass in a higher register?

Although I cannot play bass, I have played the bass book in a show using my wind controller. Ironically, if I hit the wrong octave button, all too easy to do on my old Yamaha wind controller, I get the same problem I described above. The note choice is right, but the pitch is not, because I'm in the wrong octave.

User Dzjang (spelling?) has made some technical posts here about what the bass chooses to play on complex jazz tunes, based on some careful testing. I think there is an issue there as well.
