DAWZY: Human-in-the-Loop Natural-Language Control of REAPER

We demo DAWZY, a voice- and text-driven assistant that translates natural-language requests intoreversible, state-aware actions in REAPER, a scriptable Digital Audio Workstation (DAW). DAWZYshortens the gap between musical intent (e.g., ‘warm the vocals’) and precise DAW edits, keeping theDAW as the creative hub. The system queries live session states, explains each change, and supportsrapid beat prototyping with an AI beat generation model and a Hum-to-MIDI model. DAWZY usesLLM-based code generation as a novel way to significantly reduce the time users spend familiarizingthemselves with large interfaces.
