I play both, they're great keyboards both. The pro has 76 keys perfect for someone who demands a more acoustic feel, lots of space for doing custom voices, a couple of rack lights, and no onboard speakers, has a high Z mike input, and off/on switch on the back, and that is the basic difference between the two. The psr9k is a great keyboard if you like the ability to do fast guitar and accordion type of things, the sound from the psr is just amazing and can be tweaked to get right up there with the tyros 1 (IMO). I love these boards, but they are in mosts opinion old and time running out. Still some may keep them forever, they do a terrific job of entertaining, and playing to a crowd of people, "not Studio work", they still are tops.

If you are looking to buy one, I'd reccommend one of two ways, If you absolutely need 76 weighted keys, then the pro would be it, If you can live without the extra keys, the psr9000 has far better sound and it maybe 100 bucks cheaper.

A lot of guys on here would probably tell you to forget the 9000's buy a 3000 for a couple hundred more, and have a new board that has usb and the newer additions.

I'm fixing to go to a new ty II and will be selling the psr (maybe) The pro has to stay for the Church, so any piano player can use it. However I'm not convinced to give up my psr untill the tyrosII proves itself. The mega guitars has inticed me, But the tyros 1 did not part me from the psr9000.

One opinion.....Mine....Lots of luck.....Pose
