Welcome to the forum, your first post. Congrats.

This question should be in the Band in a Box forum, Windows or Mac whichever you use. I'll give you a response here anyway.

You're asking two things, chords and feel. Biab is designed to do exactly what it's name says. Be your backup band. Real musicians will rarely play a song EXACTLY as written, different players like guitar or piano will play different inversions or add a passing note or whatever because they think it sounds better. That's what Biab does too but you still have some control over that.

Right click anywhere in the chord grid and select Song Settings. On the left of that window see Force Song to Simple Arrangement and check that box. Also under the Edit menu see the checkbox Jazz Down the Chords. That will stop Biab from making too many changes to your chords. Even with these controls Biab may still make a few changes. If that happens regenerate the song again and you may have to do that several times until you like it. Once you like it freeze the tracks so a regeneration won't wipe that out.

A strength of Biab is the fact that regeneration will change things up a little and many people like that but if you don't want that then use the Freeze option. You see that when you right click on an instrument name and look for Track Settings>Freeze Track.

As for the feel that is controlled by the style you choose, either Midi, Real Tracks or both.
