  • Easy navigation using the mouse and keyboard.
  • Feature-rich MIDI editor.
    • Support for importing VSQX (Vocaloid 4) tracks.
  • Selective backward compatibility with UTAU.
    • OpenUtau aims to solve problems with fewer steps. It is not designed to replicate UTAU features exactly.
  • Extensible real-time phonetic editing.
    • Includes phonemizers for different phonetic systems (VCV, CVVC, Arpasing, etc.) in many different languages (English, Japanese, Chinese, Korean, Russian and more).

    • Unlike UTAU, there is no need to change your system locale to use OpenUtau.
  • Smooth preview/rendering experience.
    • Pre-rendering allows OpenUtau to render vocals before playback, saving time during editing and tuning.
  • Supports ENUNU AI singers. See the ENUNU wiki page for more info.
  • Easy-to-use plugin system.
  • Versatile resampling engine interface.
    • 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.
