[RE-UPLOAD] Diode Ladder Sine Shaper part 2 - Exploring Analog Audio Synthesis, episode 12

Re-uploaded because the first video was accidentally rendered with burnt-in captions. Sorry about that!

Schematics and supporting material are on the project GitHub as usual: https://github.com/kennykb/kevins-cav...

In this video, I get to the point where I can design my own diode ladder and am comfortable explaining it.
Sorry about the length; it's heavy on the analysis (including computer-based analysis). I'd seen other videos on diode ladders, but never seen one actually explaining the design, rather than taking someone else's component values and demonstrating it. Simply presenting someone else's design never quite satisfies me. Making this video was quite a journey - I didn't know myself where the design process would take me!
