lrd,

Yes, it would be nice if BB REalTracks didn't ever play a natural 6 on the V7 chord in minor keys, and we do plan on improving that in the future.

In the meantime....
You can get around that issue by typing A7b9 for the chord, instead of A7. (in other cases, where you're not wanting b9 or b13, you can type A9). All these embellishments only happen with "plain 7 th chords", so you can get around them by typing something more specific in cases where there is a clash with the melody for example.

Have Fun!
