If I don't remember it wrong, the Tyros styles have been modifyed unofficially
by the users, and not by Yamaha?
Also I think I've heard that they do not sound anything like the Tyros played
on the PSR's.
In fact I seem to remeber that the Yamaha lawyers insisted that users should
take the styles off of the web pages not so long ago, and is'nt it true that
there was a big fuss among the Yamaha users because of this?

Anyway, happy playing on whatever keyboard brand we choose to play on
