Dario Sanfilippo -  Constructing realities

# OFL 1 – 14. May 2021, 17-19h

The talk presents the most recent outcomes of the author‘s research on musical complex adaptive systems (CASes). The first part focuses on the concepts of adaptation and complexity within the framework of CASes and suggests a clear identification of the term in the musical domain. This analysis involves a distinction of the notions of context and information between the engineering field of information theory and the philosophical one of radical constructivism. We will conclude this section by showing that, in this approach, information and context are mutually determining. Then, we will introduce distributed adaptation, a technique that is related to the notion of evolvability in biology and genetic algorithms and that has significantly increased the complexity and long-term variety in music systems during autonomous evolutions. This technique distributes adaptation across higher levels and allows the system to reorganize the relationships among its agents and their structure circularly while interpreting and constructing its context. To conclude, an autonomous live performance piece from 2019-2020, Constructing realities (homage to Heinz von Foerster), which implements the theories mentioned above, will be described showing DSP processes and techniques that relate to evolvability, autopoiesis, fitness, and complexity through agent-based modeling.


“Open Feedback Loop” is a series of talks and workshops happening as part of the project “autonomous systems” run by mur.at. We present and discuss works, tools, practices and thoughts that question autonomy, systemic and eco-systemic theory and interdependence, including contributions from different fields such as sound art, digital art, game design and performative art. The series is free and open to the public and offers an open space for inspiration for everyone interested in this field. All events are held online exclusively via „big blue button“, entry link is sent upon request. Info and registration: suonoreale@mur.at
