  - Pre-rendering allows OpenUtau to render vocals before playback, saving time during editing and tuning.

- Easy-to-use plugin system.

  - Compatible with most UTAU resamplers.

### 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.
