Just finished reading DDIA, can't recommend it enough! I learned a lot of new info in every single chapter even for topics I thought I had a firm grasp on. Great job Martin Kleppmann!
This is such a cool project, especially the principles behind it (open hardware!).
As with anything, there's prior art, so everyone should _chill_ :)
Being passionate about synthesis, I have to mention vector synthesis which has a similar vibe in terms of interaction. More like simple mixing between sounds but nonetheless really neat and powerful.
