Loop Fracture Loop

An free improvisation between players of two augmented instruments, both with tunable machine learning. Accorsi plays an augmented saxophone, whose sound is processed through effects that are controlled by an audio-reactive machine learning system. The same system is used by Kiefer in the feedback loop of their string instrument, the Xiasri. Both instruments use a novel reinforcement learning system, NISPS, that the player trains through performative exploration and expression of musical preferences, with the interface built into the instrument.
