Bill says it all Folks! I couldn't have put it better myself.
That is not to say I don't like my Tyros 3 - I do, particularly the Ballads, and Pianos but unlike Bill, I find some of the Super Articulation sounds irritating especially on some of the the guitars which to me sound like scratching or squeaking but the SA can be switched off, so I can live with that. It is the endless button pushing of the operating system I really hate. I guess I've been spoiled with 'User Friendliness' of the KN7000.
However, the World moves on and we have to move with it whether we like it not and that is the only reason I now have the T3.
