Conductr

AI-directed generative MIDI — play anything, Opus arranges the band. Conductr is a browser-based instrument that generates four tracks of real-time MIDI output (drums, bass, melody, harmony), driven by your playing and shaped by a Claude Opus 4.6 AI musical director. Say "make it funky" and the arrangement changes. Play softly and the band pulls back. No audio synthesis — connect to any DAW or synth via Web MIDI. Conductr operates on three timescales simultaneously: Conductr is the open-source project nanassound/conductr (https://github.com/nanassound/conductr) by nanassound, released under Apache-2.0. Ion packages it unmodified from commit 576bdd654725, adding only a manifest, an icon and a storage compatibility script.
