I haven't played either keyboard. I happen to own the PSR 740. I was kind of surprised when I read the specs on the PA-80 that there are only two rhythm fills. The PSR-9000 has four rhythm fills. I think there's a lot more you can do with a song when you have four fills as opposed to two. Two rhythm fills might sound repetitive. Does the PA-80 have multi pads like the PSR 9000? There are a lot of cool things you can do with the multi pads.
