Has anyone had any experience with this board or the EXR5? Soundwise, how would you rate it? How do the keys feel? Looking at the features and specs it seems like a great board for the price. I'd be upgrading from a Casio WK-3500 and the problem I've encountered is, the polyphony is a little low for me. And there's other little things I'm nitpicky about. The EXR3 seems like something I would be happier with.

Another thing I wanted to know, does anyone know if there's an online version of the manual. Roland doesn't seem to have it on their website.
