It’s hard to say based on your first experience, but I think it could just be bad luck. However, I write Brazilian jazz that uses all sorts of complex chords so I have never attempted a song in BIAB that didn’t have them.

When in the very rare case we find a provably wrong RealTrack, we send an email to support@pgmusic.com and they do some programming fix and issue a patch.

So my suggestion is work with BIAB a little more and see. You clearly understand music theory far better than most, so you may notice things that others let pass.
