Renaud Bougueng Tchemeube, Jeffrey Ens, Philippe Pasquier
Abstract
Calliope is a web application for co-creative multi-track music composition (MMM) in the symbolic domain. It is built to facilitate the use of multi-track music machine (MMM). The user can upload Musical Instrument Digital Interface (MIDI) files, visualize and edit MIDI tracks, and generate partial (via bar in-filling) or complete multi-track content using the Multi-Track Music Machine (MMM). Generation of new MIDI excerpts can be done in batch and can be combined with active playback listening for an enhanced Computer-assisted Composition (CAC) workflow. The user can export generated materials as MIDI files or directly stream MIDI playback from the system to their favorite Digital Audio Workstation (DAW). Calliope can be used for creative ideation and for exploring alternatives of musical phrases in composition.
