What I see in the livecoding scene is the combination of rather complex programming with rather simplistic music - relentless techno beats ;-) I would like it the other way around. > I personally like Extempore, but I couldn't get it built on my Windows > machine, the OS X install had some issues with Jack and timing, and my > Linux distro had a few issues too.
