Hi John
Yes, there is a difference in the sound. To me that's the main thing. A full rich tone. Being able to layer 3 right hand sounds.
I really feel that as a player switches from one brand to another that, while sometimes it might seem ackward and more than a bit frustrating in the beginning, that given a little time, this kind of switch will prove to be very favorable.
At first, I actually missed my PSR2000 over the Tyros. After a few weeks I changed my mind on that one too. The 2000 is an excellent kb, but, John one you get used to your Tyros, you're gonna be spoiled forever. haha
Enjoy that new toy. It's great to move into new gadget's and toy's.
Best
