Honestly I personally love watching Peter play,...but is he the best demonstrator? In that respect I would say for my needs when watching a demo not so much. I would rather see all the features "thoroughly demonstrated" in more detail then just listening to a great player of which many watching or listening couldn't come close to ever playing like that and this benefits no one. Instead if you can show people who are potential buyers what the "average player" would be able to do with the instrument and make them say to themselves..."Hey that's interesting I think I can do that at home" it would make them more inclined to purchase the KB. Otherwise your just listening to a nice concert,.... why not show younger new players what can be done regarding today's music styles too to get them interested? I think Yamaha's market strategy to older folks will shoot them in the foot this time around, let's hope now......

all the best.
