How does it work?
The fundamental principle behind The BodySynth is a phenomenon known to physiologists since the turn of the last century. That is, contracting muscles produce a measurable electric current (EMG) directly proportional to the strength and duration of the muscle contraction. The device's stand-alone programable processor converts these varying microvoltages into MIDI which will trigger samplers, syhthesizers etc. With practice, virtually any surface muscle can become a sophisticated MIDI Controller. A wave or a wink, a jab or a jump, they can all play/control music in real time.
The BodySynth system was designed to allow complete freedom of movement. The user wears a small Body Unit (approx. 1X2.5X4 in.)) that amplifies the EMG signals (four channels are available to sample four different muscles).Thin cables connect the Body Unit to comfortable electrodes worn wherever the user chooses. Although this necessitates a certain degree of customization for the user (depending on the location of the sample area) it gives the user a choice of unique movement combinations that will generate a personal sound or look.The Body Unit and performer are connected to the Processor Unit offstage via a standard wireless guitar/audio link.
The Processor Unit instantly transforms the incoming EMG signals into virtually any MIDI command. These commands may be programmed and saved within the Processor Unit to be connected to the MIDI device of choice.
