Operations is a computer generated audiovisual solo performance piece.
The starting point for this piece is the programming of traditional drum machine grid patterns, a type of musical score. This grid is translated into a series of Jitter matrices on multiple mixer channels. Each of these source matrices can be interpolated through nine different sets of values. The source matrices may then be further transformed via inversion or randomization before finally being added together to create a master grid. The master grid is then projected on the screen as a visual representation of the currently playing pattern. However, this pattern is never static, as on a traditional drum machine, but can be continually and seamlessly altered via the mixer.
This projected grid is then subjected to a series of visual transformations, some automated and synchronized to the beat of the audio program, some as a consequence of performer control. The resultant images accumulate on the screen, creating a series of āpaintingsā that depict the virtual space of the drum pattern through time. These scenes are organized in a database, such that the performer may control the timing and flow of the performance.
