Legacy Plugins

This is a list of all plugins for UTAU that have been tested in OpenUtau. Many popular plugins haven't been tested yet, so please update the list if you try plugins that aren't shown.

Note that some plugins themselves may have problem running on non-Japanese systems or other situations. OpenUtau being compatible does not guarantee your setup is compatible. Also note that OU's compatibility with specific plugins may change over time as it updates, so this list may be out of date.

Fully compatible

• AutoPitchWriter
• AutoVibrato
• frqeditor (May need to manually specify a resampler in the options beforehand)
• Humanizer
• iroiro2 (Doesn't open for some people?)
• Lyric Parser 2.1
• omakase2020
• RandomVibrato
• UNotePad
• UTAU Plugin Launcher
• VibratoStocker
• Extended Pitch Editor/拡張ピッチエディタ (Works with a few bugs, except for mode 1 editing)

Compatible with adjustments

• Freq Tracer (A note placed on the piano roll is needed to get FreqTracer to run. You also need to adjust pitches some after the plugin has run, and only works in "Mode 2" mode.)
• Lab2UST - A note placed on the piano roll is needed, and offsets the results. If you try to load a frq at the time of writing, you will not get any result

Incompatible

• envedit/拡張エンベロープエディタ - Works, but OU can't keep complex envelope changes intact (anything beyond what attack/decay can emulate), so basically useless
• flagedit/拡張フラグエディタ - Opens, but changes don't go through
• PrintMOV Style Tuning - Opens, but doesn't change any pitchbends
