OpenUtau

OpenUtau is an open-source singing-synthesis editor for arranging notes, lyrics and expressive parameters. It is useful for creating vocal sketches and working with compatible singing voicebanks. The editor does not confer a license to every voice or model it can load. Voicebank compatibility, pronunciation data and permitted use must be checked separately, particularly when a production will be distributed commercially.

Audition the instrument with the actual musical part, including its velocity range and register. A sound that is attractive in isolation may need a different balance once other instruments enter.

Voicebanks and rendering dependencies are separate; check their licenses and compatibility. Installing the editor alone does not supply every singing voice.
