Disklavier

I have a smart pianosoft diskette and cd.
If I want to copy a couple of tracks from the Diskette and CD onto the piano and use the Browser to control it, can I ?  If so where do I put them as they have the same names albeit different data types.    Can I convert the CD track to a wave and still have the Piano run them together ?  Can I copy the diskette on and leave the CD in the drive (second choice).
