Abstract: This article details the development of a computational patch designed for real-time processing in the composition of Chronos IIIc, originally written by Brazilian composer Roberto Victório for solo cello. In this version, the piece incorporates an additional layer of electronic elements. Initially, we provide a historical and structural analysis of Victório’s compositional project. Following that, we explore the functioning of Somax2, a computational system dedicated to real-time improvisation embedding reactive multi-agent interaction and an AI model based on machine listening and statistical learning. Building on this understanding, we present the process of electronic realization of the piece, investigating how the parameterizations of available modules can replicate the interactions envisioned by the composer between the cello and the orchestra in one of the versions of the work. Finally, we share results obtained during the execution of the design, highlighting relevant aspects of the performance.
