I've downloaded a few of the Yamaha IDC styles, both 'premium' & regular. Though a bit pricey (at 6.95 for 'premium' & 4.95 for the rest), I think the brand new 'premium styles' (currently 21 offered) sound as impressive as the terrific sounding preset internal Tyros2 styles. On the other hand, the 29 remaining styles (at 4.95/each) appear basically just re-hashed styles already previously available for Tyros1. Strangely enough, the 4.95 styles don't even include OTS (1-4) settings, as they originally did when offered for Tyros1.

The primary advantage the 4.95 styles have compared to the original Tyros1 versions is that their balance levels may be better tweaked to match Tyros2, and they also offer nice new and/or altered intros/endings.
