Eurorack Knob Idea

Eurorack is very cool and I totally understand the appeal of having physical devices to interact with but one thing I never understood is how you can recreate a specific configuration you liked later. Do you manually document every connection? Or just take pictures?

Once it's gone it's gone. That's part of what I like about analogue modular synthesizers. It's a liberating approach to doing music if you embrace it for what it is.
