It sounds like you might be hitting the "PLAY" shortcut rather than "REPLAY" one when you repeat the song. By hitting PLAY, the song is completely regenerated whereas REPLAY keeps everything the same. Unfortunately, if you close down BIAB and then restart it later, a new bass line will be automatically regenerated.

It might be worth your while considering using RealBand because once tracks are generated, they stay fixed until you choose to regenerate. This even carries through into saved files. However, since the RealBand SEQ files are audio-based, a RB file is much much larger than a BIAB file.

Alternatively, once you have generated your music and printed the score, save it as a wav file (Audio >> Render midi to stereo wav file). You could then load the wav into Media Player (or Winamp, etc) and play along with it. The score and the track should then match. You could then also use a programs like LAME and Audacity to convert the wav file to an mp3 so that it is smaller.
