Basically the PSR S910 and PSR 3000 work exactly the same. about 95% of the features are the same.

I used to own a PSR 3000 and now have the S910. The S910 has all the latest sounds and styles. the sound quality is a substantial difference.

the PSR 3000 is/was a great board. but the S910 is just basically the newer version with updated sounds and features.

It has every sound from the Tyros 2 and a god portion of sounds from the Tyros 3 including all new synth sounds and pads.

mp3 player/recorder, better keybed, proper Guitar strumming in the mega voices and multipads, new drum kits etc.

And like I said, if you know how to use the PSR 3000, you can instantly jump on the S910 and you will be able to navigate around just as easily without having to learn much...
