Nigel, it may depend on the key signature of the song. I am of the understanding that RealTracks phrasings are recorded in several different keys. The performer may have included different variations in the material depending on what key it was being performed in. Try changing the key signature (transposing) and regenerate and see if the performance changes. Also, try transposing your song into the same key that the demo is recorded in and check if there is a difference.
