The Sweet! Soprano Sax is on the "CD" that comes with the Motif ES. You will have to load it into the Motif ES. The Motif ES has a Smart Media slot or you could load it via USB to Device. You will probably want to get an external Hard Drive or a Thumb Drive which you can load the Sound Library from the CD ROM onto then transfer them to the Motif ES via the USB to Device slot. Or if your computer has a Multimedia Card reader for Smart Media (you could also purchase a Reader), you could load the Sound Library onto it. Although you will find that the entire contents of the Sound Library will NOT fit onto a 128 MB Smart Media Card so choose your Voices wisely. Either that or like I said use an external HDD or Thumb Drive, etc. that holds more than 128 MB of data. PS: A 512 MB Thumb Drive is relatively inexpensive as are many external Hard Drives. A good Thumb Drive that will work with the Motif ES is the Lexar Jump PRO Drives. Any Thumb Drive that does NOT require a "Hub" driver should work okay.

Best regards,
