Developer Builds Self-Hosted AI Music Studio with Editing and Stem Tools

A developer has created Miso, a self-hosted local AI music generation and remix studio built on top of audio.cpp. The tool supports multiple AI model families — including ACE-Step, YuE2, and Stable Audio 3 — each specializing in different tasks such as full song generation, instrumental creation, stem separation, and audio-to-MIDI transcription. A key feature is 'repainting,' which lets users replace only a selected segment of a track's waveform rather than regenerating the entire song. Miso also includes a guided prompt builder that translates a unified set of controls into the varying input formats each underlying model requires. The project tracks takes, lyrics, stems, and generation history within a single project structure, allowing users to retrace their creative process.
