Disklavier

I found this in the operating manual:

You can add a Disklavier piano performance you recorded or on 
commercially available SmartPianoSoft software to the playback of songs 
on your favorite CDs. 

So its ok i guess; I wont have the diskettes reader unit so probably I'll have to copy the floppy to the pc and from there on on a usb stick I'll choose the 
appropriate file...
