I have the Bluray. The voiceovers near the start initially kinda annoyed me, but I got more into it over time! Definitely worth checking out if you're into this kind of stuff.
Thanks, saw it last night. Not too bad, but the filmmakers sure missed a lot of low-hanging fruit. They spent a lot of time talking about music and not much time playing it, they overemphasized the Buchla/San Francisco stuff, and they missed the disco era entirely. (Sorry, say what you want about disco, but if you make a movie about electronic music that ignores people like Giorgio Moroder, you're just wasting your own time...)
They also could have done more to make it accessible to people who didn't already know a lot about music synthesis.
