Obscurantist #72: Auto: Generative Orchestra

Thee Obscurantist created an application that generates the fundamental materials for a composition based on a modal, structural design. 
The application first decides:
piece length (bars), number of root centers (modulation), number of phrases, meters, tempi and orchestration.
Next the application decides: mode, number of melodic cells, dynamics.
These generated materials are then combined to form the composition with only slight modifications, and supporting orchestration.
This 19:00 composition contains 480 bars, 18 parts, 3 mode centers, 11 melodic themes
set of random variables not used in this piece:
silences, chord density, technique, gestures.
The audio was realized digitally with the Ableton Live Orchestra Pack.
