Bests & Worsts Reviews from Amazon

Tried this instrument out in the store and could not figure out what the difference was between this one and the 520 I previously reviewed on amazon. Sound qualities, voices, layout, display, and software all seemed identical to me to the 520. Finally, after a direct inquiry to Yamaha, I was told that the only difference between this model and the 520 was that the 530 contained 10 more rhythm sequences. So, if you're one of those who would use this instrument heavily for recording and composition, and just could never find the right rhythmic background, you can try this one and see if one of their ten extra sequences works for you. If you're like me, however, who use the keyboard mostly for performance purposes and only occasional composition and recording, it really isn't worth upgrading. If you're diligent enough and have the software (pretty much any layered music recording sequence will do; I happen to use Cakewalk 4), you can make and save your own rhythms anyway on either keyboard. For a more detailed review of other features this keyboard has, check my review out on the DGX-520...aside from the extra rhythms, it's exactly the same.
