OpenUtau DAW v0.1.0-alpha.3

OpenUtau DAW v0.1.0-alpha.3

This alpha focuses on the parts of the editor that should feel immediate in a
DAW: auditioning notes, typing lyrics, using shortcuts, and returning to the
same place after closing the plug-in window.

What changed

• Piano-key audition now starts immediately, releases cleanly, and stays stable
  while a key is held. It still travels through the VST output and the DAW
  mixer.
• Space controls FL Studio except while typing in an OpenUtau text field, where
  it inserts a space normally. Command/Control+Space and F12 remain FL Studio
  shortcuts. OpenUtau keeps undo, redo, selection, and note deletion.
• Backspace edits a focused lyric or text field and deletes selected notes when
  no text field is active.
• Closing and reopening the editor restores its page, active voice part, zoom,
  scroll position, and pane layout. When moving between plug-in instances, each
  instance remembers its own page, part, zoom, and scroll position.
• Resize cursors now remain visible while hovering over pane dividers on macOS.
• Preview buffering no longer causes delayed, crackling, or broken-up piano-key
  tones with large host audio blocks.

The macOS arm64 build was tested by hand in FL Studio 2026 with two OpenUtau
instances, Teto English and Japanese voicebanks, Adachi Rei, mixer effects, and
a separate drum instrument. The container suite also covers 44.1, 48, and
96 kHz rendering with several host block sizes.

Downloads

• macOS arm64: tested in FL Studio 2026 on Apple silicon. Ad-hoc signed and
  not notarized.
• macOS x64: experimental Intel build for macOS 14 or newer.
• Windows x64: experimental. The packaged editor and VST3 validator tests
  pass; hands-on FL Studio testing is still pending.
• Linux x64: experimental native VST3 with a separate editor window.

Every package includes its own .NET runtime. Voicebanks are not included.

Current limitations

• One embedded OpenUtau editor can be visible at a time. Multiple plug-in
  instances still render, save, and remember their editor views independently.
• Notes are entered in OpenUtau; the plug-in does not accept DAW MIDI input.
• Voicebanks, resamplers, and external models must be installed separately.
• The macOS package is not notarized. Windows, Intel macOS, Linux, and DAWs
  other than FL Studio on Apple silicon still need broader hands-on testing.

Installation

• macOS
• Windows
• Linux

Verify the downloaded archive against its SHA-256 file. On macOS, use the
bundle-specific quarantine command in the installation guide rather than
disabling Gatekeeper.

Licence and source

The VST adapter and combined package use GNU AGPLv3. Upstream OpenUtau remains
MIT licensed. The release includes a matching corresponding-source archive
with the pinned OpenUtau and JUCE source trees.

OpenUtau DAW v0.1.0-alpha.2

OpenUtau DAW v0.1.0-alpha.2

OpenUtau DAW puts the OpenUtau editor inside a VST3 window. Editing happens in OpenUtau while the DAW handles transport, saving, mixer routing, effects, and export.

This release fixes the Windows editor package, bundles the matching Windows Desktop Runtime, and adds Intel macOS and Linux x64 builds. It also fixes tag validation and checkout ownership in the release workflow.

Downloads

• macOS arm64: tested in FL Studio 2026 on Apple silicon. The build is ad-hoc signed and not notarized.
• macOS x64: experimental. Built for Intel Macs running macOS 14 or newer; not yet tested in a DAW.
• Windows x64: experimental. The packaged editor opens in the smoke host and the VST3 passes Steinberg's validator, but it has not completed the FL Studio render test.
• Linux x64: experimental native VST3. The editor opens in a separate window, and the package has not yet been tested in a Linux DAW.

Every package includes its own .NET runtime. Voicebanks are not included.

Current limitations

• Only one embedded editor can be open at a time in a DAW process. Multiple plug-in instances can still render and save independently.
• Notes are entered in OpenUtau; the plug-in does not accept DAW MIDI input.
• Voicebanks, resamplers, and external models must be installed separately on each machine.
• Hosts other than FL Studio on Apple-silicon macOS have not completed manual acceptance testing.

Installation

• macOS
• Windows
• Linux

Verify the downloaded archive against its SHA-256 file. On macOS, follow the bundle-specific quarantine instructions in the installation guide; do not disable Gatekeeper.
