Be sure to add me to your favorites list Yamaha SY77 European Chart Sound Set on Floppy Disk, In Original Yamaha Jewel Case with Rear Artwork This is a set of sounds for the Yamaha SY77 keyboard MIDI synthesizer workstation, European Chart, with 128 new voices, on floppy disk. This is a new replacement double density floppy disk, placed into a very good condition original Yamaha jewel case made for this set, plus it has the original rear artwork as well. The original disk that came in this jewel case was bad and never worked, but I kept the jewel case and placed this excellent-working replacement disk into it as seen in the photos. Both the case and the rear artwork in it are in great condition. There is a wide variety of sounds in this set. These are on a double density disk floppy disk that loads into your SY77 drive. The disk is completely new, except to load the data onto it of course. It's of the double density type, as that's what this model synthesizer strongly prefers, as the high density types often fail, or never work to begin with. This disk will come in this original Yamaha case from 1992, as seen in the photos. * Note, please make sure that your SY77 disk drive is working correctly before purchasing this disk, as the floppy disk drive is the first thing to fail on these types of keyboards, which are more than 25 years old now. If you've just bought an SY77, it's best to try to save to and load from a blank disk first to make sure it works before you try a disk like this one. If it doesn't work, it's FAR more likely that the drive is bad, than the disk. Thank you! Please check out my Store!
