This is definitely significant. I find these demos extremely impressive. Those brush drums sound hyper-realistic to me. The grand piano, the vibraphone, the vocal demos, they're first rate.

This is a major improvement over the Tyros 3. I think this is more like Tyros 4.5. It looks like Yamaha went way beyond a perfunctory upgrade.

You get 50 new styles, hundreds of new voices including several dozen new drum kits and a killer grand piano, and a new vocalizer + many more goodies.

I feel for you guys who need 76 keys. It must be very frustrating that this keyboard doesn't have them.

It's going to be a painful year or two, waiting for the successor to my PSR-S910 to come out and hoping that as many of these improvements as possible make it onto my next keyboard.
