I guess you need so much recorded material to cover all the possibilities.
That's where Melodyne and ARA comes in handy, just edit the midi notes in one track and the audio changes in the other.
That's how BB will need to work eventually, move the RealChart notes and the RealNotes will move.

You can also drag the midi RC into RapidComposer with the same chord track imported from BB it will then refit the midi to the notes you need, but you will need to output it through a Virtual Bass.
