Hi Jose,

yes the Live Grand piano in the T2 is the same as in the Tyros1.
I don't know about the Psr3000 though.

Tyros2 has two new Power drum kits that are a noticable improvement over the T1 and the Psr3000. Played in styles they do sound more "live like".
I'm not sure about the basses.
However all styles have been reworked and sound much more "Live" to me.

I also feel that the T2 has much more presence than the T1 or 3000.

Hope this helps.

Eric
