Yesterday, I went to a music store to check the Ketron XD9 out, I also have tried the Yamaha PSR-2000.

Ketron XD9:

Sounds:
Very impressive, The sounds are the best i
I've ever heard,The Saxophones sound very realistic, and the flute is amazing, I couldn't find a bad sound on the XD9, all the sounds sound very natural and real.

Styles:
Very nice, the styles sound like a real band, they don't sound like a keyboard at all.

User friendlyness:
The XD9 is pretty easy to use, but not as easy as the PSR-2000.

I think the Ketron XD9 is a terrific keyboard, It is definitly gonna be my next board.
And I recommend anyone to check it out.

Greetz,
Marcel
