Yamaha CS-80 Synthesizer Sound Selection Circuit Analysis

I had the idea to do some videos breaking down how specific circuits or sections from different vintage synths work in step-by-step detail, and here's my first one, about how preset, memory, and panel sound selection works in the notorious/legendary Yamaha CS-80.

This video is meant to be more "educational" than "fun" and if you personally don't think it's fun (or musical) enough, that's OK!
It also requires at least a basic understanding of a few key electronics theory concepts to follow.

If you'd like to read a written version of this explanation and look at the diagrams/schematics in more detail, you can find it on our blog here:

We're working on another (somewhat more fun) CS-80 video that should be up soon!
