Abstract:

A 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.
