Larry,

It might be a good idea to store the S900 styles (that you use) that aren't on the S910 (that is, if you are planning on getting one) in a flashdrive folder ...they should work perfectly in the latter.

When I went from the 3k to the S900, there were a few styles from the former missing on the latter.

Many of the new S910 styles are from the Tyros3...plus, I imagine most of the T3's styles should work with a bit of revoicing, if necessary.
