Every version I found of Naima is in Ab concert.

There are several ways in BIAB to transpose. When I get to a computer, I can give more detail. I use a method you don’t have with version 2015. But I think you should do Options, Preferences, Notation and look for the pull-down settings for Transpose. Select tenor sax.

If the problem here is that you know the tune and how it should sound, but BIAB is not playing quite right chords when they are complex like in this tune, then turn off Natural Arrangement. However, I don’t remember if version 2015 had that.

Your last few posts indicate you have a knowledge of music theory., so I’m starting to be more puzzled. Is your report that the chords are not quite right, or that the pitch is not quite right?
