It's been a very long time since I used ACW. But if I remember correctly.... you have to tell it to send the file it creates back to BB where you then select the style you need.

In the tunes I have used it on, one was pretty accurate, while the rest were not. In fact, I ended up simply creating the song from scratch in BB. It was something another writer had sent to me to add a part.... ACW wasn't even close, so I had to listen to the song, learn it, and type out the chords and bass notes needed. I wasted more time trying to get ACW to "do right" than it took to actually type in the chords and changes to recreate the song in BB.
