I have 2013, and can confirm that BIAB will grey out a track name or "white" it out.

As both Noel and Matt have said, a track name that is white does not exist in the chosen style. If you look at the style with Stylemaker, the track will have no patterns nor does it have a real track (green) or super-midi (blue).

If the track name is GREY, the track is disabled in the song. When you open the song click ALT-F2 and on the left you will see a column headed "On?". If the box is not checked, there will be no sound for that track. Check the box and hopefully it will work. This function is song specific.

I use it occasionally if I like the style but don't want to hear the strings, for instance. I just uncheck the box, and that track is quiet.
