That demo has been posted before (by Diki, I think), but it's still a great demo by a super performer. However, in this case, we are paying way more attention to the performer than to the arranger kb (and for good reason). Sadly, very few of the old, arthritic fingers on this board are going to be able to match that performance so before you shell out that 4k for that PA3x, just remember that Marco playing a toy Casio is probably going to sound better than you on that PA3x.
Love that guy's playing, though. Funk/jazz - not for everybody but fun and exciting when done by a master (like Marco).
