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.

As well, please note that OU's compatibility with specific plugins may change over time, so this list may not be completely accurate.

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.

Fully compatible

• AutoPitchWriter
• AutoVibrato
• EasyOtoing (Might need more testing. Will need to reload OU to reflect oto changes, probably doesn't work on non-shift_jis banks?)
• 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
• UTAU Plugin Launcher
• VibratoStocker
• Extended Pitch Editor/拡張ピッチエディタ (Works but is a bit glitchy,except for mode 1 editing)

Compatible with adjustments

• Freq Tracer (Need to adjust pitches some and only works in "Mode 2" mode.)

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
