Avid has officially launched Sibelius 2025.4, the third major release of the year — and it's packed with performance improvements, creative enhancements, and long-requested workflow updates for composers, orchestrators, and educators alike.

If you have an active subscription or an up-to-date perpetual license, the update is available now for download on Windows, Mac, iOS, and Android via your Avid Account.

Score Subsets & Dynamic Parts: Smarter Ways to Manage Staves

Score Subsets continue to evolve! If you’re dealing with large orchestrations or need rehearsal scores, this update gives you more flexibility than ever.

✅ New in 2025.4:

• Independently toggle transposing score state in each Score Subset and the full score.
• Improvements to absolute text sizing for consistency across subsets.
• ‘W’ shortcut now cycles through all Dynamic Parts + the full score of the selected stave.
• Staff text now applies to all voices when entered using passage/system selection — perfect for making dynamics and technique markings universal.

Usability & Stability Fixes

Avid continues to prioritize user feedback with key fixes aimed at making your Sibelius experience smoother and crash-free.

Highlights:

• Fixed crashes from:
• Rhythm dot usage in passage selections
• Playing back older scores (4+ years)
• PDF exports
  
  
• Inspector UI now behaves correctly with hidden objects
• Alt+Click copy-paste accuracy improved
• Tab numbers and tremolo triplets now behave as expected
• Grace note spacing restored after 2025.2 bug
• No more unwanted music respacing in legacy scores
• Font changes on blank pages no longer jump you to the top

Kontakt 8 Player Integration

Sibelius 2025.4 now works beautifully with Kontakt 8.3, unlocking support for modern sound libraries.

? Now supported:

• Spitfire Symphony Orchestra
• Jacob Collier Audience Choir
• And more libraries with non-numeric IDs

With a proper sound set, Sibelius will automatically load these libraries, streamlining playback without tedious manual setup.
