These items do not exist. There are no demo disks and no OS disks like with the WK series from generalmusic. I have questioned Solton numerous times but all they say about demo's are that there are many good song disks available and you could use one of these as your demo. My point to them was they could maximize the sound potential of the X1 if they would write a few songs using the X1 sounds at their best. Well, they haven't listened yet. I also think it is not smart not being able to recall all the factory sounds and regestrations without having to load them from a disk that you've had to save. Even though the factory installs these on the hard disk, you can accidentely erase the hard disk and then you have nothing!
