Well, I wasn't going to comment much on anything about the demo, mostly because I thought someone was pulling my leg...

OF COURSE there wasn't any original voice there. OF COURSE it sounded like bad Alvin and the Chipmunks. OF COURSE it wasn't even the right chords, and the style was nothing like the original. (It often helps to go back and listen to the original BEFORE you choose a style!). But other than that...

Thanks for playing...

But as a demo of the S900.... well, I wouldn't buy one for that harmonizer, for one thing, and if that's Yamaha's idea of Southern Rock, well, I wouldn't use one in Dixie if I were you!
