It appears that at least half of the demo styles are pretty much the same as the Tyros 4 in this genre, but probably some minor differences in the intros and other voice parts.

From the ones I recognize from the Tyros 4, it would be safe to say the demos were played live, but many sections were the intros to the styles. I too enjoy and play many styles in this category and look forward to the new Tyros 5 styles and improvements.
