Hypermusic!

Article Abstract:

MIT Media Lab professor Tod Machover has invented several hyperinstruments, which are half computer and half instruments. Hyperinstruments merge the sounds of traditional instruments and synthesizers via user-friendly interfaces. They task the computer with the technical aspects of playing but leave the emotional and artistic elements to the users.
