All I can say is Biab does not recognize all possible chord variations and if you're using Real Tracks then you're dealing with what was actually recorded in the studio. If you find a RT that is not playing the proper chord notify support about it, they have issued patches for this before. With midi it's usually not a problem. If that chart says Biab recognizes that chord then with midi it should play it. BUT...

This is controlled by the style and using or not using that checkbox to "jazz up or jazz down" the chords. You also have the "intelligent arrangement" feature to play with too. Biab is designed as an intelligent song creator so sometimes it simply decides your chord doesn't fit so it does it it's way. It's not a dumb "play it exactly how you input it" kind of thing. Sort of like a real band with real players would do. You get a good player on whatever instrument and they may decide on their own to make a few chord subs.

Also regenerating can give you different variations on the chords so listen carefully, if you suddenly hear what you want freeze the tracks and don't regen again or you'll lose it.
