openutau-daw

OpenUtau DAW enables users to run the OpenUtau editor as a VST3 plugin inside digital audio workstations like FL Studio. It allows real-time editing of notes, lyrics, pitch, and singer assignments while leveraging the DAW’s transport, tempo, mixing, and project management features. The plugin saves project data within its own state, ensuring it travels with the DAW project file. Multiple instances maintain independent audio and project states. Currently in early alpha, it has been tested on Apple Silicon Macs with FL Studio 2026; other platforms (Windows x64, macOS Intel, Linux) are under development or require further testing. Limitations include no MIDI input from the DAW and only one embedded editor window active at a time. Voicebanks are not included. Installation guides are provided for macOS, Windows, and Linux. The project uses Docker Compose for building and testing, with OpenUtau pinned as a submodule and VST-specific changes applied via patch. Licensing combines MIT for OpenUtau and AGPLv3 for JUCE components.
