Be sure to add me to your favorites list Factory Set Restore Disk for the Yamaha SY85: Performances, Voices, and Drum Patterns on Floppy Disk, for Use with the SY85 Only. BEFORE YOU PURCHASE A DISK, PLEASE READ THE BOTTOM OF THE PAGE WITH THE * Thank you. This is a floppy disk of the Yamaha factory set sounds for the SY85 synthesizer keyboard / workstation. This is a diskette that is loaded directly into your SY's disk drive, this is NOT an SY85 itself. This disk allows you to restore / reset your SY 85 with all of the original factory set sounds, which include: Performance Banks Voice Banks Drum Patterns This is a new double density disk (the type this synthesizer strongly prefers as the later high density disks either soon fail or never work to begin with), never used, except to load the data of course. The appearance of the disk you get will vary, as I usually have several different brands of disks available, since DD disks aren't easy to find these days, but it will be unused and in excellent working condition. This is a floppy disk only, not a synthesizer or anything else included. This floppy disk is what you need if you would like to reset the factory sets, or if you've lost your data altogether. There are 3 data files on the disk, which allow you to: load ALL sounds, load just the Synth sounds, and load just the Drum Patterns. This is also great to have just in case you lose this data in the future too, as you can always reload it after using another sound set or sample disc. AGAIN, PLEASE READ THE PARAGRAPH BELOW WITH THE * Thank you. * Note, please make sure that your SY85 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 SY85, 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! Thanks for looking! Please check out my Store!
