>> Noticing that Biab doesn’t live up to its’ promise to play “all the chords” and really only knows 7 chords (7 7th chords to be precise) was another big let down.

Dzjang,

That's a feature called "Natural Arrangements", not a bug. You can turn the feature off Prefs-Display'Natural Arrangements-Never. That would turn it off for all songs, until you enable it again.

You can turn it off for a single song (via SongSettings button or Edit-Song Settings)

With the feature off, if you type | Gm9 | C9#11 |, the rhythm section will play those exact chords. With the feature on, the rhythm section will think more like | Gm7 | C7 | and play some embellishments based on those chords. This is how real musicians play (try handing Herbie Hancock | Gm9 | C9#11| on a leadsheet and see if he plays those exact chords) , but if you want the exact chords you are specifying, then turn that feature off. (similar to telling Herbie - please play those exact chords)

btw, that feature just affects jazz styles (not pop, or country)

Have Fun!
