"You can create UserTracks with Toontrack and UJAM,
whatever you are using for your pop styles just make them into UserTracks then make your own styles in Biab using these UserTracks.
This maybe a quicker way to as these will just generate up rather than keying chords in EZKeys."

Pipeline's assertion that you can turn EZ Keys and UJAM instruments into BIAB User Tracks is tantalising.

Is it a real thing? That would be more useful than just using EZ Keys and UJAM instruments themselves? If so, please explain how.

I would want the full range of chords and am not interested in doing 30 minutes of playing to get that.

If it's as easy as you suggest, I'm sure lots of BIAB users would love to do it so please let us know how!
