So is this an arranger demo, or was that an SMF? I didn't see any calls to the arranger buttons (but he might have used footswitches) and it's difficult to see whether he's playing in pianostyle, or just playing to the backing.
The song's execution is OK, but I was expecting just a bit more flash. Such a simple tune, played so simply, really deserved something more than just piano all the way through, or more flash from the piano if that was the choice. And finally, a decent camcorder audio recording (or at least, married to the video later) to illustrate what so many of us have said about Yamaha drums... Piano - nicely defined, crisp, cuts through. Drums - wooly, and lacking in definition. You can't blame the recording (it would have made the piano wooly, too). Priority #1 on the NEXT T-series, IMO (and yes, I know it's a 9kPro!).... better drums.
But for a user video, it's definitely at the top of the heap, and perhaps should be a reminder to even the many manufacturers that let out god-awful videos, that a modicum of care and attention, even on consumer grade equipment, can make a video that doesn't embarrass their arrangers (as most of them do).
Nice job, Esh...
