I guess you understand Billy that Real Tracks are pre-recorded music 'phrases' recorded in a studio by musicians and saved as an audio file format (not MIDI), so changing single notes is not straightforward (Melodyne as you mentioned is one solution).

The team here have recommended Real Band which allows you to regenerate any selected section of a track until you (hopefully) get a musical phrase that fits better. BiaB can only regenerate an entire track.

Of course, you'll only be able to regenerate and receive results from what has been pre-recorded, there's no infinite possibilities.

Hope this helps
