Make music as you walk, dance, run around – “…a unique performance instrument for motion-capture midi control, featuring extensive customization to enable a wide range of musical and visual applications. Setup and operation is simple, intuitive and quick. The suit is modeled on the human skeletal form using rotational sensors placed on the joints. The GypsyMIDI simply plugs into a MIDI interface and arm movements are converted into a real-time stream of MIDI data.” Link.
