Timing and playing pattern immediately come to mind. User Tracks are just as prone to clash with some styles and not play to a style's groove as normal RealTracks are. BIAB provides hundreds of guitar RealTracks and users constantly struggle to find one to play in their project correctly.

Two things with your User Track process I don't fully follow are:

1. Why you choose to render the individual User Track Template instruments and export them into the DAW rather than a single stereo mix?

2. Why you're using live drums rather than select a BIAB style drums?
