New approach to digital piano actions

And just because I decided to now embark myself into this anymore (solenoids available for free!!) let me dump here a number of things which I wanted to study but never did, in case they can be useful to the next tinkerer.

CyberGene

CyberGene Humans are human. Leave them with such a big pile of cash and they will end up on a luxury yacht covered in white powder and surrounded by dubious women 🤣

I would not oppose 😃

I considered something like that, not for keys but for pedals--it's easy for digital pedals to feel like you're pushing on a spring and not a whole lot else, so being able to simulate the inertia of the damper assembly (and apply it conditionally depending on things like number of keys already pressed) would be really neat to add
