Ryan, yes the Genesis comes with the CD installed, it is not an option. Also, the price for the Genesis will be about $400.00 more than the 9000 pro or the SD1 is selling in most stores and less than most stores sells the Technics KN6500 and the Roland VA76, so I don't think this is an overpriced keyboard considerating a 100 what system, 64 MB, a CD burner, 3.5MB hard drive and Vocal harmonizer and a host of other great features.
The Yamaha DX keyboards have the standard 6 track yamaha sequencers found in other lower priced Yamaha keyboards such as the PSRGX76, the PSR282 and the EZ30 keyboards. Nothing fancy in the new DX500. The sounds are about 600 and are better than the lower models but not as many as the PSR550 and the PSR2000.00 There are music data bases on all and the ability to layer and split which has been off the lower priced Yamaha's is now available on all new models. Also, when you select the voice, style, song buttons, you will have the whoe switch light up which is a nice touch and on the replacement for the PSRGX76 (again I can't remember the name) there is both a data wheel for changing sounds and a keypad if you like.
