Yamaha DX7s

In response to feedback from a number of people, I've expanded the sections I created on the Yamaha DX7s synthesizer. I'll continue to add information on this classic FM synthesizer, as time allows. To date, I've produced specific pages covering the following:

• How to replace the battery in a Yamaha DX7s
• How to restore Yamaha DX7s factory voice and performance data
• How to run the Yamaha DX7s internal diagnostics
• Yamaha DX7s factory internal voices and ROM cartridge voices

You can download DX7s SysEx patch files from the Yamaha DX7s SysEx factory voice and performance patches page.

I've also added downloadable copies of the following Yamaha DX7s manuals and technical documents to the Music Equipment Manuals page:

• Yamaha DX7s Owner's Manual
• Yamaha DX7s Service Manual
• Yamaha DX7s Parts List
• Yamaha DX7s Circuit Diagram

Please note:
All the manuals available on this website are, as far as I'm aware, out of print and/or for obsolete equipment. If you are the copyright holder of a manual on this website and would like me to remove it, please let me know via the Contact page.
