My understanding is that the basic process for realtracks shouldn't be too different.

Thanks Cerio for this, I wasn't familiar with usertracks. I remember hearing about them years ago.
This would definitely answer a number of questions I asked if the process for creating RealTracks is the same/similar.

If the process is the same then the tracks could be recorded in the musician's home studio.
It seems the musicians would be given a set of changes to play.
And further down on the page with the link you gave, it seems that the longer the chart of changes given, the more complex the chords can be in the final RealTrack.

The video you linked to had four keys covered. It seems that was sufficient enough for BIAB to
then add in all the remaining keys.
