Much better to do this in Real Band. RB gives you 48 tracks to play with and you can add all kinds of midi/Biab/Real Tracks or Real Drum parts to it. The midi file shows up with each instrument on it's own track and you just select a style, right click on an empty track and add a Real Track or Drum part. The really cool thing is you can then change the chord grid, change the style, pick another empty track and do it again. You still have the other one to compare it to. Many times I may use several different styles in the same tune for different parts. The RB chord grid works the same as in Biab so go into that and correct any chord changes, put in your part markers and you're good to go. By correcting the chords I mean that RB and Biab both will detect the chords from a midi file but it's doing that from analyzing the instruments not from what somebody actually entered as chords because you don't enter chords into midi files. That may be possible in some programs but I've not seen it in the hundreds of midi files I've downloaded. Chord detection from midi files can be fairly good but they're not Biab files where someone entered exact chords.
