I am a composer of Brazilian jazz and I want the complex chords chords played exactly as I wrote them, so I have Natural Arrangement turned off. For the average BIAB user I would guess the opposite would be better; let the program enhance the smoothness of the sound by simplifying progressions and making better voice leading.

In your case, I think you need to ask the course leader and set yours the same way that person has his or hers set.

I addressed this a bit in my article in the Tips and Tricks Forum: When BIAB Plays Chords That Are Not Quite What You Wrote. I know you saw it.
