I just took a wild leap and traded my i5s and the is35 towards an SP500. I had to throw a few bucks on top, but only a few. I'll keep this piece in my studio for recording, and see how it fares. I like the grand piano sound, I like the feel, and although I hate the touch screen, it will not be much of a factor at home. Live is another story, altogether. Too bad there is no way to import styles ..... or IS there? There is no disk drive, and I haven't cracked the book open yet. I have a bunch of i series disks with styles that I'd love to use, if I could.
Anyway - give me a few days to plunk on it, and I'll tell you what I think about it as a studio controller.
