Gary, obviously all the styles were not specifically made for the PSR-3000, so I assume many simply do not sound the way they are intended, or am I wrong? I'd hate to have to run over 50,000 styles through midi player, and/or edit the non compatible styles.

Perhaps this was already setup for you and the 3000 and was part of the package? Either way, it's a good deal, and I'm sure it's like getting a new board. Keep us posted as you explore all those styles, and have fun with them.
