If I want to apply a style, then I use the midi to generate chords when it loads and to grabe the melody, and sometimes a solo line. I strip out the other tracks or channels and then let BIAB take the other tracks.

If you do not do this, then a style is likely to become a problem with the already established tracks of a full midi file, unless you are very careful to choose and match midi song and a style.

Typically you can easilly determine the melody track or channel of the midi and use the sequence button to delete the other track or to get down to a lead sheet, then you can begin to apply styles to play the what if game as far as applying styles back to the song.
