I'm more interested in his music tool Masagi. I made a useable baseline within 5 minutes of using it. I like how intuitive it is - like when you just slide the piano notes to make them longer and place a dot for a note in space on a "graph". Too bad he seems to have made it on a whim and looks like he isn't going to develop it further. I'm sick of Buzz crashing on me out of the blue when I was on a roll producing nice tracks and loops every day. Reinstalling didn't help at all. Good thing I saved all my presets until I figure out what's going on.
As for the sculpting tool, it looks like it will be great when textures support is added. If its as intuitive as Masagi then I suspect It'd be grade A.
