HI: BEBOP
The PSR9000 & 9000 PRO have the good sound Jedi
talks about & also has the quality built into the keyboard
also, but they are heavy PSR9000 51lbs. 9000 PRO 45 lbs.
no speakers in the PRO .
The vocal harmonizer is great in both boards.
I have the Technics KN5000 & the 9000 PRO
I love the 9000 PRO GREAT board.
Have had the PRO 15 months & no trouble with it yet.
It took me a little while to get used to the OS on the Yamaha
as they do things different then Technics, but now I find it to
be as easy or maybe easier to use then the Technics.
If you have any questions send me a Email & I will try to help.
Enjoying the 9000 PRO
Denny
