Help with BIAB Bluegrass style

[Steve Schaefer]

Okay, I just got and installed BIAB on my Mac G3 laptop. Since I play mostly bluegrass these days, I punched in the cords of one of my favorite songs and selected the Bluegrass style. It was the most ridiculous thing I have ever heard. The base line was all wrong, and two of the instruments were a piano and drums. I listened to some of the jazz demo songs and they sounded pretty good. Am I doing some thing wrong or is there a better bluegrass style I can down load some were?

Thanks
Happy Holidays
