A couple more observations.

The music rest is the same as the PSR3000, but the slots look a little more sturdy. Also the rest seems to be lay a little lower so your sheet music will get a tiny bit less in the way of the audience.

I loaded a bunch of original Tyros 2 styles onto my USB. Then I played a bunch of them. The same styles that had voices that wouldn't play on the PSR3000, those voices don't play on the PSR-S900 either. I guess this is because there are still many Megavoices on the Tyros 2 that aren't on the PSR-S900.

The voices on the style part of the keyboard are pretty much the same, but some of the styles are reworked to sound a little better. Where the PSR-S900 shines in comparison with the PSR3000 is with the right hand voices which features the S.A. voices.
