Loops That Listen: A Voice-Controlled Dynamic Drum Looper with AI Variation

Résumé fourni par la source

Live looping constrains musical dynamics. The same pattern cycles indefinitely, while a performance demands response and variation. CHULOOPA is a real-time drum looper that resolves this tension directly. The performer beatboxes patterns, and the system varies them in response to the live musical energy. A dBFS-mapped RMS measure, “spice”, drives selection from a pre-generated bank of five variations. These variants are generated in parallel by a grid-based decoder-only transformer and sorted by deviation score into a predictable creativity spectrum for the performer. At each loop boundary, the variant matching the current spice level is selected without interrupting playback. CHULOOPA demonstrates that audio-responsive AI variation can give a loop a controllable range of complexity while keeping it anchored to the performer’s original pattern.
