1-The over sound is up about 5 notches above the PSR3000.
2-Working with the Music Finder -- When you exit or save a song the Music Finder does not default to the top, instead it stays where you were working last.
3-I know you can use an external recorded, in many cases a better one that’s in the S900 --- but what a connivance to have it all in one package, love it.
4-The buttons do have a different feel but In my short period of playing this keyboard I do not find them a problem.
5-In order to see the window properly you must sit high or elevate the back end of the keyboard. When you elevate the back end the music rack is almost perpendicular. N.G.
6-I do love the weight.
7-The screen is the same size (I think) but it is brighter than the 3K.
8-I am not sure why they made two areas on the Main screen a darker color, it limits how you adjust the screen.
9-The Video out put only works well in some cases. Instruments show good, but the bottom of the page is missing. The main page is split, part of the bottom is at the top. Any way of adjusting this. And the red colors are blurred.

I welcome any thoughts, John c.
