Welcome to the forum.

What you are hearing sometimes depends on the style. Also, if you are using MIDI you are more likely to hear exactly what you wrote than if this is a RealTrack(s).

Some things you can try:

Experiment with other styles.

Use a more complex chord, such as E9 (if that sound is acceptable). This leaves less to chance. For example, I often use a 9 chord rather than a 7, to prevent the program from playing 7(b9) or 7(#9).

Repeat the chord each measure.

Look up Natural Arrangement and turn it off for this song, or globally.

You say you found Simple. There are a few places that applies. One is in the RealTracks picker. Another is in I think Preferences, Arrange where you can look for something like Simple or Jazz Down. I’ll look for the specific command later.

There may be a few other things but try those. BIAB is only trying to make a nice accompaniment, and it was originally developed for jazz.

Freeze means it will not try any other choices, so only use that if it plays what you do want. You can freeze individual tracks, so if only one track is a problem, freeze the others and keep regenerate/play; you might get lucky (then freeze that track).

BIAB can be challenging. You’ll get there.

What genre is the song? What style did you try?
