To my ear, and granted I don't typically type in my own chord progressions, everything that comes out of Band in a Box sounds excellent.

But MusicVillain recently write a post that made me realize I don't really understand what impacts how what effects how good the RealTracks styles will sound over a given chord progression. She wrote

I recently found this Soloist RealTrack #3198 very good, and I want to listen to the track and learn about the guitar arrangement.

However, I can't. If I load this track to BiaB, BiaB will chop the track into pieces, then re-assemble the pieces into a new track, which sounds very inconsistent and unpleasant.

I was wondering:
1.) Are the Realtrack soloists recorded against particular chord progressions that are guaranteed to sound stylistically "good" because they capture the expertise of the original recording artist's choices for that particular sequence of chords ?

2.) If that is the case, will choosing certain chord sequences possibly sound less tasteful (or possibly srendipitously even 'better') when a user enters a new, different chord progression.

3.) Does a similar concept hold for RealTracks styles that are purely accompaniment, and don't have a soloist ?

If you choose to share an answer, please if possible include some specific examples.

TIA
