Oh man, lots of great/exciting links!
Not exactly that way, but perhaps some elements of what Otomo Yoshihide does, throwing actual drum/percussion stuff in the mix with a turntable. I also like the idea of scratching too, but not ala q-bert or someone super flashy like that. It would be really fun coming at it as a drummer(/pianist) as there’s a lot of physical, and mental, dexterity when it comes to rhythm in my hands.
I’m also leaning towards actual physical vinyl for the time being, but the inclusion of digital vinyl opens up the possibility of a vinyl driven Cut Glove system, which would be cool as shit!
