This is a player that can play song data (MIDI) stored on floppy disks. It has a built-in XG-format MIDI sound source and can also be used as a MIDI sound source by inputting MIDI data from an external source. I have confirmed that it powers on and produces sound when data is input externally via the MIDI port. Other functions have not been confirmed. The drive's operation has not been confirmed due to the lack of a floppy disk containing data. When I inserted a blank disk I had, the display showed "1". This is a used item, so there may be scratches, stains, and signs of use. Accessories include only the manual and power cord. No box is included. Please confirm any questions before purchasing.
