This is super cool! I would love to see the specific mapping of keys that were used which were said to be inspired by the accordion. Even though that's a way less interesting detail than the way that the spoon picks up the distances and the "bit banging" used to achieve 8-bit precision on the modulation from two 4-bit connections.

Sounds pretty swell!

I wonder if the spoon controller could be adapted to send modulation parameters to arbitrary instruments via a midi port. I would buy a spoon modulator if it was reasonably priced. It would be a great add-on to a piano style keyboard without pitch bend or mod wheel etc

I don't know for sure, but I'd bet that it is similar to Qwertuoso: https://www.linusakesson.net/software/qwertuoso/underworld.p...

Safe to say it's the same as qwertuoso, muscle memory isn't that easy to remap, even if you're Linus Åkesson. I forget if it's a type B or type C, he mentions it on his site somewhere.
