• Dec 1, 2025 - 14:27

Hi everyone,

We're pleased to bring you a small update to MuseScore Studio: version 4.6.4. This update includes critical fixes to improve app stability, security, and performance. It is recommended for all users.

It also includes enhanced features to support online sounds, ensuring the best compatibility with Cantai for performing lyrics in playback.

You can get the update right away via MuseHub or here at MuseScore.org.

Changes in 4.6.4

Online sounds

  • Various optimisations and improved messaging for online sounds (Windows and macOS only)

Playback

  • VSTs now receive playback time position (enables synced video playback with the score)
  • Notated tempo BPM values are converted to playback speeds with greater precision
  • We've switched back to ALSA as the audio server on Linux (PipeWire is still available via Preferences)

Engraving

  • Slurs from grace notes to tied non-grace notes now stop at the first note of the tie
  • Parentheses around noteheads no longer touch ledger lines below the staff
  • Restored the ability to create frames with negative margins (not recommended)
  • Fixed display of invisible multimeasure rest numbers
  • Fixed horizontal spacing of cue notes under a trill line
  • Fixed hiding of courtesy clefs, key and time signatures near a section break
  • Fixed hiding of measure numbers when all instruments are hidden
  • Fixed vertical alignment of voice 1 rests at "gaps" where rests in higher voices were deleted
  • Fixed regression where measure numbers collided with brackets around single line percussion staves

Chord symbols

  • Fixed rendering of accidentals when using the "Legacy MuseScore" style with a font other than Edwin
  • Fixed vertical layout of chord symbols and RNA that include parentheses
  • Fixed double layout problem that caused unnecessary stave separation after edits to chord symbols

Interaction

  • Single notes now become selected after being pasted
  • Fixed issue causing slurs to change shape unnecessarily when other objects are moved
  • Fixed regression causing grip anchor visualisations to not update on adjustment

UI

  • The Welcome dialog no longer appear over app update dialogs
  • Restored the "Align with preceding dynamic" checkbox in the Properties panel for expression text
  • Opacity / alpha transparency is now available in the color picker dialog
  • Custom colors saved in the color picker dialog now persist between launches on Windows
  • The modern print dialog is now shown on Windows 11 rather than the legacy Windows dialog
  • Fixed regression causing some error dialogs to appear multiple times despite "Don't show again" being selected
  • Fixed regression causing menus to appear in the wrong position on Linux
  • Fixed regression in the Percussion panel where pads were drawn with hard corners instead of rounded
  • Fixed regression where the special characters dialog was modal, preventing interaction with the score

Import/export

  • TablEdit: Fixed import of pickup measures and measures with gaps in voice 1

Accessibility

  • Fixed keyboard input in spin boxes when running under XWayland on Linux

Plugin API

  • Fixed Spanner::endElement() and Tie::endNote() to return the end element rather than the start element
  • Slur offsets (slurUoff1 – slurUoff4 ) are now properties of SpannerSegment and return correct values

Stability

  • Fixed crash on deleting instrument after using Tools > Implode
  • Fixed crash on pressing Esc after entering notes via MIDI keyboard
  • Fixed crash on adding a system marking to a score with large time signatures
  • Fixed crash on pasting multiple fermatas where the lowest would go below the bottom staff
  • Fixed crash on pasting the repeat-measure symbol onto a measure with notes in higher voices
  • Fixed crash on entering an invalid chord symbol
  • Fixed crashes during use of network connections

We saw several reports of crashes in MuseScore 4.6 that were caused by older versions of MuseScore 4 being present on the same Windows machine. This might affect you if you used earlier versions of MuseHub, which used to install MuseScore to a different location. If so, please make sure the old versions are fully removed before you upgrade to the new version. If you do want to use multiple versions of MuseScore 4 on Windows, consider using the portable EXE for past versions, and use MuseHub or the standard MSI installer for the current stable release.

Please note, using multiple MuseScore 4 versions is not a supported configuration on any operating system. In particular, when you switch to an older MuseScore 4 version, you may experience strange UI bugs until you use Help > Reset to factory settings. This does not apply to running MuseScore 3 and MuseScore 4 on the same machine, which is supported via the standard installers.
