That brings back nice memories, I designed some of the early Serato scratch hardware. I didn't work for them directly though, so never did manage to find out how the vinyl timecode worked.

Cool! If I ever run across you IRL I’ve got to buy you a beer and pick your brain :D

I've started a UI for magic wormhole:

https://github.com/sneakypete81/wormhole-ui

It's GPL, cross-platform, native (Qt) and uses the same Python library as the Magic Wormhole CLI.

I've tested it on my own devices and it installed and worked without a hitch. Thanks.

That's fantastic! I was about to add a request for just that in my above comment, but forgot. Keep at it!
