Be sure to add me to your favorites list Yamaha SY85 "House Techno" Sound Set (128 Performances, 128 Voices, 10 Waveforms) on a Floppy Disk. For the SY85 Synth Only, It Will Not Work for the SY77 or SY99. This is a set of sounds for the Yamaha SY85 keyboard MIDI synthesizer workstation, "House Techno", with 10 new waveforms, 128 Voices, and 128 Performances, on floppy disk. These sounds are of the techno type and are on a floppy disk that loads into your SY85 drive. The photo is just a graphic, as the disks I have will vary in appearance. The disk you get will be 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. NOTE: If you have just purchased an SY85, please check out the disk drive, load and save data to a good disk, before purchasing this. That way you will know if your drive works, as they are the first thing to fail on these model keyboards. If your drive works, this disk will work fine. Thank you! Please check out my Store!
