A friend of mine who plays the same as me has just ordered a PSRSX 900. He said that when it arrives he would like me to transfer his registration bank and some of his user styles to the new instrument. Will they work as they did on Tyros 4? I'm thinking along the same lines in getting one myself.I will keep the Tyros 4 as a back up with view to possibly getting serviced overtime. Am I doing the right thing ? Thankyou John.
For the most part the registrations and styles from the T-4 to the SX-900 will work fine. Most likely some voices and/or DSP's will not be exactly the same, or may not exist at all and will need tweaking. What's cool is you'll have both to compare.
IMO, the T-4 was maybe the best in the Tyros series. Something about it, but it had a beautiful lush sound. The SX-900 is a great lightweight but powerful arranger, that I think you'll be happy with. The OS is basically the same and the combination of touch screen and buttons are awesome. Just needs your personalization, and you're good to go. Again, you'll have the advantage of trying it out on your friends SX-900
Good Luck, and keep those drinks away. Electronics and liquid don't mix
