VIRTUAL DJ uses the tracking capabilities of the Gesture and Media System to allow one or more users to use space as an audio remix or performance tool. Users literally wave their arms, and as if by magic new audio loops are accessed, synthesizer filters are opened, samples are played, and drum loops are started. Simultaneously robot lights follow the users, dynamically changing in relation to their position and the audio. The piece can be performed by one or two local users in a large space, but with the help of CANARIE, a version with one local performer and one remote performer can be performed over the internet at two geographically-removed sites. In this scenario, two identical presentations can be held, each with the ghostly presence of a remote interactor moving sounds and lights in tandem with the local performer. Virtual DJ is a prototype for a new type of club- and network-based performance, and can be used by anyone from absolute musical neophyte to the expert performer. Virtual DJ seeks to find a new mode of performance and editing: one that is spontaneous, capable of changing dramatically from one performance to another, and above all, seamless.
