"Constructing Realities" (tape, live spatialization)
Constructing Realities is a performance piece for an audio complex adaptive system and a performer interfaced via microphones and loudspeakers. The DSP network is provided with a sensing infrastructure in the sound domain, and an adaptation network recursively reshapes the DSP topologies, relationships and the sensing mechanisms themselves. The result is an autonomous system that responds to external and internal conditions and explores a continuous (though limited by the software data type) behavioral space that generates long-term coherence and formal developments. The performer, another agent within a larger recursive network involving microphones, loudspeakers, environment, and DSP, operates by altering the position of the microphones in the space; i.e., by altering the physical topology of the network.

"Order from Noise" (tape, live spatialization)
Order from Noise is a performance for a complex adaptive system. An autonomous recursive DSP network with elementary information processing and statistical mechanisms is activated with one millisecond of background noise from the environment; the signal, the sole sonic source, recirculates incessantly undergoing continuous transformations while the DSP network reshapes its relationships and structures. The system is left unattended for as long as the performer considers a sonic evolution completed; then, the system is reset and reactivated several times with a new impulse, showing how radically it can diverge from a perceptually identical initial condition.

"Single-Fader Versatility" (live)
This work explores digital feedback systems with minimal self-regulating mechanisms and the idea of systemic mapping. The parameters of the agents in the network are all controlled by a single fader. Within each agent, these parameters are mapped so that control pairs act in a positive or negative feedback fashion regarding their specific characteristics and targets. The performer explores the parameter space by adjusting the fader when needed, and by sometimes switching the positive or negative feedback relationships between the control pairs.
