• Easy navigation using the mouse and keyboard.
• Feature-rich MIDI editor.

  • Compatible with most UTAU resamplers.
• Runs on Windows (32/64 bit), macOS, and Linux.

What it doesn't do

• While OpenUtau can do very minimal mixing, it will not replace your digital audio workstation of choice.
• OpenUtau does not aim for Vocaloid compatibility, except for some limited features.
