This was made 100% on my Casio MT-500.  It's very short, but it was made as a demonstration of the keyboard's abilities on my youtube review about the superdrums keyboards.  I did add reverb to the drum track during post, other than that, everything else is exactly how it sounds coming out of the keyboard.
