Thanks for the kind words everybody.  I do enjoy that song.
Donny, yes, I'm playing the Tyros 4 and love it.  I see you're playing one too now.  I never saw a need to go to the T5 and sure don't need a 76 key Genos.  I don't think I'd sound much if any different the way I like to use a keyboard.

Scott I can't believe the T4 was something in the back of my mind to buy and waited this long vs all the many kbs I went thru with no success,.....in a way I am glad I waited I don't regret any of the previous, I chalk it up as a learning experience. Tyros 4 really sounds terriffic and I agree with your thoughts all the way.
