the programable part of the machine, the tracks themselves are comparable to a midi file
I think part of the point of this project is to avoid electronics and digital tech in the final machine. personally I think it's what makes it so interesting, he's interested in the mechanical design and engineering aspects, not the digital ones
It’s a lot cheaper to set up something like this in a virtual space - it also takes up a lot less space.
VCV Rack 2 is a free way to very closely replicate the experience of building eurorack module synthesizers - without the cost of buying all the rack gear, and without needing to devote space IRL to assembling and organizing all the parts.
I could imagine a similar approach for designing and operating musical marble machines like this (in fact I’d almost be surprised if something doesn’t already exist, akin to roller coaster tycoon’s coaster design tools!)
