Be sure to add me to your favorites list Yamaha SY77 "Classical" Sound Voice Set on Original Yamaha Floppy Disk, in Case This is an original Yamaha floppy disk diskette for the SY77 synthesizer keyboard. Cosmetic condition of the disk is very good (and it's now over 20 years old), and it works great in your SY77's floppy disk drive. This is a set of sounds for the Yamaha SY77 keyboard MIDI synthesizer workstation, Classical, with 64 new voices, utilizing both the FM synthesis and AWM sample capability of the SY-77. These are on a floppy disk that loads into your SY77 drive. The disk is in great working and very good cosmetic condition, and comes with a floppy disk case that shows some age and scuffs, but will help keep your disk safe and dust-free. These sounds are of an orchestral type, with various strings, brass and woodwind sounds, both solo and grouped, plus some choir, piano, harpsichord, harp, various tuned percussion instruments, and other percussion as well. * 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!
