If you had asked this question about Biab only we would have told you the best program for this would be Real Band.

RB will generate all the same parts that Biab can using the same RT/RD's or midi styles. It also uses the same chord grid that Biab uses although you can't directly copy the chord grid from one program to the other but you can enter the chords just like you would in Biab.

Inside RB simply right click on an empty track. In the menu that pops up are your options to generate Biab parts. That means your method would be to first create the chord grid then right click a track and generate your parts.

Since RB has 48 tracks you can generate lots of Biab parts including different versions of the same part like maybe you want an RT strumming guitar part or piano part. You can generate 5 different tracks with each track generating a different part from 5 different styles. Pretty cool. Then you can mix and match all those tracks to finally arrive at your final mix.

Also, watch all the RB videos.
