Be sure to add me to your favorites list Rock Collection, Samples / Voices / Sequence, Sound Floppy Disk for the Yamaha SY99 Synthesizer. This is a sound disk for the SY99 synthesizer, and is a backup floppy disk in excellent condition. With 8 new rock samples, 30 new voices and 1 new demo song sequence. This is a diskette that is loaded directly into your SY-99's disk drive. Load all data go yes for the sounds, and multi song run for the demo. This disk contains 3 rock guitar samples, 2 bass samples, 1 kick drum sample and 1 snare drum sample, 1 flute sample, 30 new voices and 1 new demo song. There is a nice set of new Rock sounds in this set. These are on a double density disk floppy disk that loads into your SY99 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. * Note, please make sure that your SY99 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 SY99, 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! Check out my Store!
