Every archive carries MuseScore General, a General MIDI SoundFont under the MIT
licence, in a SoundFonts directory — which is most of the download size and all of the
instruments beyond the four built in. Beside it, a Dictionary directory holds the
NAIST Japanese dictionary (BSD-3-Clause, jpreprocess's build): what reads kanji
lyrics, and what gives a melody composed from lyrics the words' pitch accent to follow.
On macOS both live inside the bundle, so dragging Auris Studio.app to /Applications
takes them along.

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.

Drums and generated parts

• Drums have their own track and editor. Dedicated percussion tracks use named drum rows
  and editable MIDI assignments. The built-in polyphonic kit supplies kicks, snares, hats,
  cymbals and toms, with shared hat choking. Composed percussion and MIDI channel 10 imports
  use drum tracks; drum tracks export on channel 10 without consuming melodic channels.
• Measure and assign drum sounds. Background analysis measures built-in, SoundFont and
  hosted instruments and proposes musical roles from their rendered audio. Apply a map for
  future generation, or retarget generated clips with an undoable command. Manual assignments
  remain available, and analysis alone changes no notes.
• Shape generated parts in the inspector. Drummer and the melodic Session Player offer
  complexity/intensity pads, phrasing controls and take selection. Each pad gesture is one undo
  step and preserves the seed. Shared drum kits retain independent settings for individual
  voices. Newly generated parts start on bar lines.

The desktop

• Audio tracks can show spectrograms. Switch from the waveform to a frequency display
  calculated in the background. It follows clip trimming, stretching and looping while
  describing the source recording.
• The window follows your appearance settings. Themed title bars bring playback and panel
  controls together. Clearer icons and panel indicators, an interface font picker, custom
  colour themes and keyboard-friendly settings selectors improve navigation. The library has
  clearer grouping and search results, and macOS panel controls align with the window edge.
• Singer controls show who is singing and what is happening. Named voice and speaker
  selection, portraits and persistent render feedback make failures and stale takes visible.
  VOICEVOX speaker discovery runs asynchronously, and leading-consonant handling fixes
  first-beat synthesis failures.
• LeapSinger joins the singing backends. Exported acoustic models and NHVSing vocoders
  render locally through ONNX, selected through a .leapsinger.json entry. Model preparation
  is documented in docs/singing-backends.md.
• Windows supports ASIO. Choose the audio backend and inspect the buffer size actually
  reported by the device. Source builds can download a missing standard SoundFont in the
  background; release archives continue to include the standard sounds and Japanese dictionary.

Files, Agent and MCP

• Autosave preserves the last manual save. Unsaved changes go to a private session
  snapshot, including before the first save. Save and Save As write the permanent document;
  closing without saving keeps the last manually saved document.
• Model tools can revise an existing project. Expanded clip, harmony, routing, effect,
  automation and file operations support local edits, with checkpoints and protection against
  conflicting disk changes. Shared schemas and tool_help expose exact arguments. Invalid
  calls receive corrective feedback, while repeated failures stop the tool loop.
• Preview and compare actual audio. Short previews are available as local WAV files and
  MCP resources. The listen tool sends excerpts to a separately configured audio-capable
  critic. The optional Python reviewer is in tools/audio-review in the source checkout;
  release binaries include the tool interface, not that service or its model weights.
  Reviews remain experimental and depend on the chosen model.

Compatibility

• Project format advances from 19 to 21. Older percussion tracks migrate from explicit
  source or drum metadata while preserving their stored notes and performance. Every project
  saved by this release uses format 21 and cannot reopen in v0.5.0, including projects without
  drums.
• Native Auris voice metadata remains version 2; existing v0.5.0-compatible voices need no
  re-export. LeapSinger rerenders can differ with the same seed; saved audio takes preserve
  the performance.
• Model calls now require add_track.kind and add_clip.name. The set_effect schema requires
  an explicit slot.
