Chris Vik in the video below explains and demonstrates how he used the Kinect to control the massive Melbourne Town Hall Organ. It contains a short excerpt from their performance together with Elise Richards “Carpe Zythum” in November 2011.
“I’ve created my own software “Kinectar” ), which allows the use of the Kinect to control MIDI devices, ie. playing notes through simple gestures and motion. The Melbourne Town Hall Organ got a referb in the late 90s adding the ability of MIDI messages to active the notes… and so, this happened.” My project blog: http://chrisvik.wordpress.com
The company that provided the control system to allow the organ to be played via MIDI are “Solid State Organ System” and can be found here: http://www.ssosystems.com
