There were some steps before the modeling process began. The existing "visual organ stop" of desert landscapes from California and Arizona had to be fit to the structure of Curran's jam. Because there are eight landscapes Ox used eight as the number of groups or "sets" of sounds. There will be four groups of musicians playing together across the LamdaRail optical network in immersive space. Ox used a MAX/MSP program modified by Holland Hopson to derive pitch and dynamic information. You can see some of these directly above. Ox then sorted the sounds into their groups using the visual cues of the above referenced graphical representations of the sound files. Each group will use the same texture map, one of the eight original desert landscape drawings, and have transparent colors which are chosen and patterned by Ox after listening very closely to the sound files.
The colors chosen to go over the landscape texture maps reflect timbre qualities and patterns within each specific sound file. Ox is using the timbre system she originally created when beginning work on the Color Organ in 1997. This list of sound/color equivalences has been growing as the Color Organ visualizes more and different instruments.
