Changelog
What's new in each Cantai installer release.
v3.1.0
Latest
September 7, 2026
macOS
Windows
For Intel Mac users
Cantai now runs natively on Intel Macs. Download the dedicated macOS (Intel) installer from the downloads page — the Apple Silicon installer won't install on an Intel Mac, and vice versa. Rendering on Intel runs on the CPU, so it is slower than on Apple Silicon; we recommend at least 4 CPU cores and 8 GB of RAM.
- Cantai now supports Intel Macs: a dedicated installer for Intel-based Macs (macOS 13.4 Ventura or later) renders locally, just like on Apple Silicon.
- Cantai now tells you when an update is available: a banner in the plugin links straight to the new installer, and an outdated engine shows a clear update prompt instead of “Not Connected”.
- More pronunciation fixes: “mazed”, “wildered”, “beheld”, “sapling”, “cobble” and the elision “’neath” now sing their correct vowels and syllables.
- Fixed a rare crash that could happen during playback while a render was running.
- On Windows, zooming with Ctrl+scroll no longer breaks the plugin window.
v3.0.2
August 21, 2026
macOS
Windows
For Sibelius users
We recommend updating Sibelius to version 2026.8 — together with this release, it makes editing a score with Cantai active noticeably smoother.
- Renders are noticeably faster: the heaviest parts of the voice engine now run on your GPU when one is available, on both macOS and Windows, falling back to the CPU automatically.
- Editing a few bars no longer re-renders the whole score — unchanged sections are reused from a cache, and a small edit now re-renders only the moments around it instead of everything that follows.
- Sibelius stays responsive while you edit: quick successive edits, batch operations like Explode, and mute or solo changes no longer set off waves of unnecessary re-renders in the background.
- Clearer diction on unstressed syllables: words like “infinity” now sing their real vowels instead of an “uh” sound — and dozens more words were tuned individually, including “tomorrow”, “forget”, “begin”, “either”, “pharaoh”, and words ending in “-le” like “little” and “double”.
- Crescendos and diminuendos now build gradually across their whole length, the way a singer would phrase them, instead of only stepping at the arrival — and loudness no longer jumps between rendered sections.
- The singers' own phrasing now carries through to the final mix: each phrase keeps its natural rise and fall, and the overall level is set once for the whole part instead of being flattened section by section.
- Voices no longer sing through short written rests, even at slow tempos.
- “Clear caches…” now lets you clear just one part, the current score, or everything — and cleared audio stops playing immediately.
- Dorico no longer freezes or crashes when closing a project.
- A redesigned controls panel and a more polished installer on both platforms.
v3.0.1
August 4, 2026
macOS
Windows
For Sibelius users
For now, choose your singers in the Cantai panel rather than in the Sibelius Mixer. Open the Cantai plugin window for a stave, pick the voice there, and it stays on that stave and is saved with the score. The Mixer lists the general voice types — Soprano, Alto, Tenor, Baritone, Bass — and the choir sounds. Choir and ensemble sounds assigned in your score are unaffected, and existing scores keep playing: a stave that named a specific singer falls back to its voice type, and you can set the singer again in the panel. This is a provisional solution — we are working on the definitive one, and we will ship further improvements as they are ready. If something still looks off, tell us through the chat on cantai.app; the more you can describe about the score, the faster we can reproduce it.
- Written dynamics now shape the singing itself — a crescendo or a forte adds real vocal effort and brighter tone, not just more volume, and hairpins ramp toward the next marking. Scores with no written dynamics sound exactly as before.
- Steadier pitch — noticeably less drifting out of tune on long held notes and long vowels, and far fewer of the sudden dives into a low growl at the start or end of a note. This is an area we are still actively improving.
- Cleaner sound — removed the clicks at the seams between rendered sections, and fixed a timing wobble that made small ensembles beat against each other.
- Clearer diction — corrected six English words (amen, forever, retain, present, Israel, Hallelujah), smoothed Spanish diphthongs into a single vocal gesture, and fixed phrase-opening consonants arriving too early.
- Sibelius: staves no longer end up without a voice or swap voices with each other after a Mixer change, “No parts found” now recovers on its own, and a render that never starts no longer leaves the plugin stuck on “Rendering…”.
- Sibelius: the “Bass” sound now loads the Ottetto bass voice (Patrick) instead of a baritone, so a Bass stave sings in the right range.
- Sibelius: for now, singers are chosen from the Voice selector in the Cantai panel, one per stave — the pick is saved with the score and stays on its stave, and the Mixer lists the general voice types and the choir sounds. This is a provisional solution while we work on the definitive one.
- Dorico: the “Auto & Cantai” playback template now ships with the installer, so Cantai is assigned to every singer automatically — and the plugin window no longer shrinks into the top-left corner on high-resolution displays.
- Dorico: fixed renders that could lose their dynamics, or fail outright, when Dorico cleaned up a file Cantai was still reading.
- The score language is now saved with the score, so different scores can use different languages and changing one no longer changes the others.
- Closing one notation app no longer stops rendering in another one you still have open.

- Sibelius: voices now load reliably even when a voice is selected before the list finishes loading.
- Sibelius: fixed a crash that could occur during automatic rendering.
