Microsoft applies to patent gesture-based MIDI interface, turn us all into JMJ
 

Microsoft has applied to patent a free-space gesture controller for a MIDI interface that could see you kicking out jams on invisible instruments. Using a Kinect-style depth camera, individual movements would be mapped to notes and played out by the games console observing the action. The company actually teased a similar function in its Kinect Effect advert, where it showed cellists, violinists and pianists all miming in front of the sensor, although we doubt the technology is at a sufficiently capable stage just yet. If granted, it means we could see plenty of intentional arm-waving in future music games, or an even more outrageous stage show from the world's most beloved Gallic synth maven.
