You have to also be careful with #5 chords as to how it is interpreted.

If you look at about page 573 in the BIAB user manual, you will see the supported chords list.

C7#5 should work (if it was in fact recorded by the RealTrack artist - not sure what gets substituted if it wasn't). But C#5 is not a "C chord with the 5th sharped", it is instead a C# power chord (1st and 5th); in that case, I enter Caug to sharp the 5th.

While not what you are asking about, similarly, you would enter a C5b (to flat the 5th), as Cb5 would get interpreted as a Cb power chord (1st and 5th) which would be enharmonically equivalent to B5 (and that's also the way it would probably show up on the chord sheet).

BIAB does have its quirks. RealTracks do not have every combination of chords played, so I have found that you either get a less embellished chord played (so instead of a C13, you might instead hear a C11 or C9 chord), or sometimes nothing gets played.

I'm sure my explanation have muddied the waters even more.
