PureJoy: PureJoy is a flexible vocal expression interface. Think of it as an audio sketchpad for prototyping harmonies, beatboxing, and other short impromptu compositions. PureJoy uses a game joystick as a physical interface to capture and manipulate vocal sounds and other "found" sound, making it a great tool for improvised musique concrète. The use of vocal sound as primary source material takes advantage our most expressive and automatic soundmaking capability, but enables a performer to amplify the number of voices they can produce, enhance the complexity of their rythms, and change the timbre of their sound. Additionally, the joystick is a familiar, playful interface that is commonly used as a manipulator for digital information.

The PureJoy operates in conjunction with the AudioPint. Video from a demo at MIT-ERS can be seen here.
