I'm surprised I hadn't stumbled across this earlier but it looks like the Jazz mutant Lemur controller finally landed itself an official Ableton Live multi-touch control interface going by the name of Mu. You can download it absolutely free direct from the official Jazz mutant Website but obviously you'll need a Lemur multi-touch controller to put it on. Apparently the whole thing requires zero configuration and is entirely plug and play. Despite the ready to go out of the box theme behind it all the Mu software still employs an open architecture meaning it should be easy to integrate into custom setups. Get it here for free.
