Be sure to add me to your favorites list Yamaha SY55 / TG55 Demosoft Version 1.0 Original Yamaha Floppy Disk, for Use with the QX5FD Sequencer / Disk Drive. This is an original Yamaha floppy disk diskette for the SY55 synthesizer keyboard, and the TG55 midi module. Cosmetic condition of the disk is very good, and it works great. The disk is in a plastic cover. For use with the SY55 / TG55, which of course has no floppy disk drive, you can load the sounds if you have a QX5FD sequencer / disk drive. I don't think there is any other way to load these sounds, as I couldn't do a bulk file load via Midi when I tried to do so. If you have a working QX5 FD unit though, you can get these sounds like load just fine. This is a great, rare find now, and a fellow Yamaha fan will really enjoy it. Thanks for looking!
