WHAT IS IT?
The MULTI-LASER GESTURAL INTERFACE (MLGI) is an open source and modular “free-gesture” controller that uses beams of laser light along with photo resistors to create a physical, fluid musical instrument. Designed while studying with Dr. Ajay Kapur at California Institute of the Arts, the MLGI attempts to bring a physical interactivity to electronic music performance. By removing the performer from behind the laptop, the audience becomes aware of the performer’s interaction with the controller, which creates an instant visual connection between the sound and the performer. The MLGI was created using Dan Overholt’s multi I/O CREATEUSB or CUI interface, which, along with the programming language ChucK, can be made to send MIDI or OSC via USB port.
MODULAR DESIGN:
The MLGI’s modularity comes out of its simple internal design. The technology used to build the MLGI can be housed in practically any material of any shape or size, and can be used to control anything that accepts MIDI or OSC protocol. Currently, the MLGI has been used as an live effects controller, an electronic musical interface, a live vj mixing tool, and even a digital tampura. The MLGI has also been used in correlation with live dance performance, and to control musical robotics.
OPEN SOURCE:
The MLGI is an open source interface. Anyone interested in building one should use the links below for detailed building instructions, schematics, code examples, and various BOM resources. If you have built your own MLGI, please send your photos or video and i’ll post them! If you are interested in owning an MLGI but are not interested in building one, please contact me for details and price information.
CURRENT DEVELOPMENT:
Bandpass Filtering for Lasers
