Jim Fogle you've got it! ACW is exactly what I have been doing right now, using its chord detection function to figure out which chord is being played on which bar of the wma source audio, so I can chop and comp these source audios in a DAW by myself.

There's only one problem: it's a post-recording action, not a pre-recording action. Meaning, if the wma file gets a bit complex, ACW will tell the wrong chord, screw everything.

Jim Fogle you know how to record a User Track, and RealTrack were recorded in the same way. A user/player is given a chord sheet, with different chords, and he play along and record, then BiaB uses the chord sheet to determine which part of his track is on which chord, so later it can be cutout and inserted into a new song based on the new song's chords.

I wonder, why PG Music doesn't give this reference chord sheet of each RealTrack to its users? The size is very small. With this reference chord mapping chart, it is 100% accurate because Brent Mason recorded the whole track based on it. If BiaB starts to generate sour notes or inconsistent octaves on any RealTracks, a user with this chord chart can simply drag the source wma to his DAW, quickly find the chord he needs, cut it out, and get it done.

I truly hope, there's a way of achieving this.
