Be sure to add me to your favorites list Original Yamaha SY77 Job Table and Global View Quick Info Sheet. This is a supplemental / quick view type of sheet for the Yamaha SY-77 synthesizer workstation. It's an original document from Yamaha and has quick, easy view detailed information on functions of this powerful synthesizer. The Job Table has quick info on various modes of the synth (voice edit mode, multi edit mode, song mode, pattern mode, utility mode), while the Global View shows a large diagram of how the sound producing parts of the synth are set up. It is one thick sheet of sturdy paper (not quite thick enough to call it cardboard) in good used condition. From the early 1990's, a helpful easy to use reference for use with the SY77. Printed in Japan! I have a few of these available at this time. This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them. Thanks for looking! Check out my Store!
