Be sure to add me to your favorites list Yamaha SY77 Basic Guidebook / Sales Guide Manual Booklet for the SY 77 Digital Synthesizer Keyboard This is an unusual booklet related to the Yamaha SY77 synthesizer keyboard workstation. It is a good reproduction copy of a booklet used to market and sell the SY 77 model, but it also serves as a quick guide for using your SY77 too, as many subjects on using and programming them are covered in a brief format. This document was made back when this was a new model, as I'm fairly sure that an old dot matrix printer was used to make the original! This is a good copy of that original rare find. It is 7 pages long and would be helpful to beginners and intermediate users of this powerful synth from the early 1990's. 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 and please check out my store!
