Don't worry, you're not the only one. I've played music for years and write music in my spare time and still found this interface to be overwhelming :)
I've been making electronic music using all sorts of software for 15 years and this seems really confusing. I think he could improve it considerably by reducing the visual complexity when zoomed out[1]. He could also create tools for making sub-modules at the patch level, but I get the feeling that this environment is going to remain pretty high-level and such things may not be so useful (as they are in Max/MSP, Reaktor, et al).
