The MLGI is a multi-laser gestural controller built and designed by Meason Wiley at California Institute of the Arts.
The controller uses Dan Overholt’s CUI interface along with an array of photocells and laser modules to send out control data, which can be converted to OSC or MIDI using various programming platforms such as ChucK and Processing.
This video demonstrates the MLGI working with ChucK, which is sending OSC to a custom built live instrument created using Native Instruments Reaktor Software. The controller is still in it’s development stages, but will be featured at the NIME conference at Carnegie Melon in June.
