Hi:
I've recently upgraded to BIAB 2013 from a much earlier version, and I'm still finding my way around. I'm having difficulty viewing bass lines in the notation window. For some reason I can view the bass line that BIAB generates in one song, but not another when I press the notation button, even though I'm using the same RealTracks. When I press the notation button I get a blank Tab line with only chord symbols down below. What am I doing wrong?
