Awesome, definitely going to look into more of those.
It's interesting, I had learned quite a bit about digital logic, and had never really applied it to much outside of controlling stuff. I'm thrilled to see that it can be applied here for all kinds of really interesting sound generation.

I had seen the Turing Machine mentioned several times; it is another on my "to get" list.

That's actually really true; like I said, it's really crazy to see concepts that I had learned about used in these really cool ways. I like that Eurorack has really become more than just VCO, VCA, VCF, envelopes and all that. If it's changed that much since the 70's, I can only imagine what it will be like in another 40 years.
