Here is some unsolicited advice from a killjoy for all those considering a SX900. The SX900 is not going to be a "night and day" difference over the old PSR-975. Let's look at the evidence.

SX900 has a better screen which is a nice upgrade if you want and need it. SX900 has a chord looper. Some pros, like Diki, tout this as a fantastic feature and it seems to be getting a lot of press. I have one on my PA900 and never use it-it's too fiddley. Your mileage may vary.

SX900 has better drums (no Revo) which are nice. But you lose audio drums-some don't care and you may be able to load them in the SX900. SX900 has better output options if you need them. SX900 has same old harmony as PSR-975. SX900 has new Playlist but it still is just a list of registrations although it may be an improvement over the old system. Sounds-very little difference. There is a video somewhere that shows a guy comparing a Tyros 5 to a 970 (I believe it was) using the 970 speakers for both. Difference? Almost undetectable.

There is a law of diminishing returns. So is the SX900 worth $600 or whatever the difference is over the 975? That is up to each individual. Diki is getting one I believe because he wants the chord looper and Roland is not making arrangers (yet) that are comparable to his current BK-9. That is a valid reason. Another valid reason is if you want the new touch screen and OS and are willing and able to pay for it. Another valid reason is you are rich and not worried about the money.

Don't think I have not succumbed to the "new keyboard fever." I am still mad at myself for spending what I did on m PA900 (in my situation as a home "dabbler"). I could have bought a guitar that would have lasted me for the rest of my life with that money. But the keyboard will either be obsolete or quit working before then. I probably should have bought a used BK5 and suffered with the screen.

But my point is-buy the SX900 if you have a valid reason as I have defined "valid" above. But if you do buy it, don't expect a "night and day" difference over your old board or you will be disappointed.
