3 Wessel, D Wright, M Schott, J 2002 Proceedings of the 2002 conference on New interfaces for musical expression National University of Singapore Singapore, Singapore 1-3 In this demonstration we will show a variety of computer-based musical instruments designed for live performance. Our design criteria include initial ease of use coupled with a long term potential for virtuosity, minimal and low variance latency, and clear and simple strategies for programming the relationship between gesture and musical result. We present custom controllers and unique adaptations of standard gestural interfaces, a programmable connectivity processor, a communications protocol called Open Sound Control (OSC), and a variety of metaphors for musical control. http://portal.acm.org/citation.cfm?id=1085213
