I spent a little over an hour today playing the new Tyros. It is better than I expected.
Of course an hour isn't enough to explore everything, so I mostly looked at the features that I use most.
First the styles--there were several new ones and they sounded very good, certainly more live than than the older ones. A lot were carried over from previous PSRs though.
The R&B Styles seemed to be much better and there were several new ones there.
The Tyros has the best Grand Piano I have ever heard outside a real one. And it's better than a lot of real ones.
I listened to it first through the speakers of a Clavinova, but shortly had to switch to headphones because other customers kept crowding around--even making requests!
There were several new and improved Guitar sounds that I liked.
The Operation was seamless and everything extremely well laid out. I liked the display a lot.
I did not investigate Registrations, Sequencer, Multipads and only briefly the mic input. Guess what, the Karaoke Girl and Speedy Mouse work as they should. Oh I forgot, there was nothing wrong with them in the 2000 either. Wrong. I also didn't check to see if it is is upgradeable by Flash. I know they advertise it that way, but I believed 'em last time so why wouldn't they lie again?

Scott, you will love this keyboard. You will take it everywhere and leave your 2K in the car. Even though there are LOTS of similarities, the Tyros has a look and feel of higher quality. (Of course it should, it costs 3 times as much).
I don't understand where the music rack will attach. There seems to be no slots for it. Maybe there is a bracket?? This keyboard was already sold so I couldn't really unpack everything.
Will I get one? Not now. Maybe when they bring out the Pro version. They should have plenty of room to put it in the same case. There is lots of wasted space.
Oh, and those Megavoices? They didn't exactly blow me away but they were nice. Starting to sound like Ketron.
