My remark was a more general one about the hype of a lot of Tyros videos with average performances, compared to someone like this Ketron player, who is really skilled. The Ketron Badinerie demo both has very good sounds AND the player shows good skills in both hands, playing fast movements precisely with the left hand also, no matter if there are pre-recorded tracks in addition. I think pre-recorded tracks are ok as long as you do as much as you can with both hands live.
IMO, the last two links you posted don't show any playing skills, neither in the Ketron nor in the Tyros case. You are right that in these examples the Tyros is more live and uses a style only, but there is absolutely nothing difficult to play here (although from other videos I know that this player is good, too). It's more about the sounds of the instruments, and in this James Last example I prefer the Tyros 5 sounds.
