RC (Radio Control) is a collaborative performance system for multiple movement artists and software defined radios (SDRs). The system enables performers to adjust the tuning and other parameters of the SDRs based on their location within the performance space and position. Video cameras aimed at the performance area feed images to a motion tracking patch in Max (software), generating location information which will be scaled and sent to the SDRs via OSC messages, controlling their tuning. Performers will have individual choreography instructions for the piece; some will be attempting to control the sounds of the radio in a specified sequence, others will have movement instructions based on the sounds they hear
