By far the best Yamaha demo sound wise to me...

I found the drums surprisingly good (Brush kit)..The Vibes are better then previous Tyros...the trumpet was ok, but a little gimmicky..and the piano..did nothing for me...seems like the old piano..

What made the demo work for me..he turned down/off the other accomp parts to give a more combo feel..

And yes 76 keys would have helped the player...the piano part (two hands) played on the right hand split was limited to close voiced piano..it suffered greatly from the limited range...
