Well for one thing, the Tyros2 lacks NTT = Guitar. That was added in a later version of the Tyros. So if the style contains a track like that, it won't play correctly.
Obviously the T2 cannot play audio styles either.
Frankly I could care less about audio styles. But I wonder what the first Yamaha was, that can play SFF2 (Style File Format 2) with Guitar note transposition?
EDIT: I think I answered my own question, and yours at the same time. Check out this page:

Jorgen has been working with Yamaha styles for a long time, his stuff is amazing!!
