Downloads

File What it holds
…-macos-aarch64.dmg Drag Auris Studio.app to Applications; CLI and MCP are inside the app
…-windows-x86_64-setup.exe Per-user installer for the desktop, CLI and MCP
…-macos-aarch64.tar.gz Portable app, CLI and MCP for Apple Silicon (Intel Macs are no longer supported)
…-windows-x86_64.zip Portable desktop, CLI and MCP executables
…-linux-x86_64.tar.gz the auris command line tool only

Every archive includes a Dictionary directory with the NAIST Japanese dictionary
(BSD-3-Clause, jpreprocess's build), used to read kanji lyrics and their pitch accent.
On macOS it lives inside the application bundle.

None of it is code-signed. macOS will refuse the first launch and say the developer
cannot be verified: open it from the right-click menu once, or run
xattr -dr com.apple.quarantine "Auris Studio.app". Windows SmartScreen wants
More info → Run anyway.

Auris Studio is at 0.x, where nothing is stable: the project format, the configuration
files and every public API may change in any release, with no migration.

Intel Macs are no longer supported. The macOS release is built for Apple silicon only, and
its downloads are now named macos-aarch64 instead of macos-universal. Because of that
rename, Auris Studio 0.18 and earlier on a Mac will not offer this update: download the
disk image from the release page once, and later updates arrive in the application again.
Windows is unaffected.

Composing with the agent

  • Add a music linter that reports problems in the score, offers the obvious fixes, gives the
    agent tools to read and apply them, and keeps ignore rules with a reason. Linted notes are
    underlined with a yellow squiggle in the piano roll.
  • Pin comments on tracks and clips and inside the piano roll, and let the agent read and
    write them.
  • Fit lyrics to melodies: analyze_lyrics counts note slots per mora, held long vowels and っ
    as a rest, checks each phrase against its melody, and returns a reading write_lyrics
    accepts note by note. Workshop composers read kanji lyrics with the shipped dictionary.
  • Give the agent read-only melody_shape and arrangement_shape checks (register, leaps, the
    chorus's lift, parts per section, fills, intro and outro length), and ask in the prompts for a
    chorus that lifts, eight-bar intros and outros, and fills into choruses.
  • Sing swung clips swung, and swing sixteenths in proportion under eighth swing, so the voice
    no longer runs straight against swung accompaniment; set_performance warns when parts
    disagree about swing.
  • Add song-wide lyrics: a timeline lane, written by the agent and shown as video subtitles.
  • Sing the particles は and へ as wa and e.
  • Tell the agent which Auris it is driving, hand CLI agents a bounded history and let them
    resume their own sessions, and launch Codex's native program behind npm and bun installs.
  • An opt-in phased composing profile (AURIS_COMPOSITION_WORKFLOWS=1) splits the work into
    score, arrangement and mix phases. The default is unchanged.

AI workshop

  • Label candidates (1B and so on) on the cards, in feedback and for the director, and let a
    direction name earlier candidates as sources whose clips are restored exactly.
  • Show the composer's own activity line, wrapped within the card.
  • Give workshop composers the user's SoundFonts, and say why a font is missing.
  • Delete conversations, and keep long references out of the transcript.

Arranging and sound

  • Add a sustain transform that holds every release on like a pedal.
  • Chord clips can put a root below the voicing and strum by note value; consecutive identical
    chords merge into one span.
  • Make physical-model accuracy adjustable for live playback and rendering, stretch-tune the
    physical piano to its own inharmonicity, and redraw the physical-model view so every body can
    be touched.
  • Fix dry audio leaking through mono external effects.

Video export

  • Caption the chord progression, and pick any colour for the note roll.
  • Fix a crash on narrow chord progress bars.

Interface and installation

  • Offer the spacious two-row top bar again, as the default.
  • Give Cargo installs an app shortcut and an upgrade command.
  • Delete installers and helper copies left by earlier updates, and sweep the staging files an
    interrupted download leaves behind.

Fixes from the November reviews

  • Keep an approved audio URL from redirecting onto the local network, ask before searching a
    folder the agent names for audio, and redact other spellings of a private path in issue
    reports.
  • Bound undo by what it holds as well as by its number of steps, answer a cancel while another
    process holds the project lock, and let conversation transcripts use their full 64 MiB.
  • Say that audio opens on Play instead of that there is none, stop warning about a dictionary
    nothing asked for, and publish documents and exports with the same permissions as their
    neighbours.

Projects are now saved as format 34, which adds the sustain transform; earlier builds cannot
open them. macOS now needs an Apple silicon Mac; the Windows requirements are unchanged from
v0.18.0.
