Spire Muse: A Virtual Musical Partner for Creative Brainstorming
Notto J. W. Thelle, Philippe Pasquier · 2021
We present Spire Muse, a co-creative musical agent that engages in different kinds of interactive behaviors. The software utilizes corpora of solo instrumental performances encoded as self-organized maps and outputs slices of the corpora as concatenated, remodeled audio sequences. Transitions between behaviors can be automated, and the interface enables the negotiation of these transitions through feedback buttons that signal approval, force reversions to previous behaviors, or request change. Musical responses are embedded in a pre-trained latent space, emergent in the interaction, and influenced through the weighting of rhythmic, spectral, harmonic, and melodic features. The training and run-time modules utilize a modified version of the MASOM agent architecture.
