In the organizer's words:

19:30 gamut inc "Dialogue de l'orgue double"
20:30 Marcin Pietruszewski w/ Lukas de Clerck "Oto Aulos"

Ancient breath and machine intelligence collide in immersive spatial performances that reforge organs and aulos alike into instruments of a post-digital aural mythology.

The Berlin-based duo of Marion Wörle and Maciej Śledziecki, gamut inc focuses on electro-acoustic and machine-built performances, sharpening a critique of mechanization, digitality, and the human in between. At CTM they present a special spatial performance inaugurating their custom-built modular windynamic organ BLACK SQUARE developed by the traditional music automaton manufacturer Decap, which unlocks new possibilities in acoustic resynthesis. Using machine-learning processes, gamut inc will re-create and project voices and sound materials through their two identical computer-controlled organ modules, dialoguing with a composition diffused over Haus der Visionäre's d&b Soundscape spatial PA-system.

"Oto Aulos" by Marcin Pietruszewski and aulos performer Lukas de Clerck centres on the creation of a new composition for aulos and computer, using machine listening and machine processing techniques to transform the instrument's live signal into a dynamically spatialized hybrid real-time environment. The aulos is reimagined as a volatile, contested sound technology whose mythic legacy resonates with today's fractured sonic landscape. The project also explores how spatial sound technologies can reshape musical structure and listening practices by embedding machine perception into real-time spatial dramaturgy.
