Hi Rafael: Don't worry, your 9000pro is still the TOP of the line Yamaha arranger and contains MORE sounds/styles & features than the PSR2000. Basically the PSR2000 is a 'mid priced' version of your excellent keyboard. The reason I chose the PSR2000 is because of it's weight (23 lbs) and smaller size (portability). If you like though, I'd be glad to trade you my PSR2000 for your 9000pro. - Scott
