DESCRIPTION
MuseScore is a Free and Open Source WYSIWYG cross-platform multi-lingual music composition and notation software, released under the GNU General Public Licence (GPLv2).

Running mscore without any extra options launches the full graphical MuseScore program and opens any files specified on the command line.

The options are as follows:

-a | --use-audio driver
    Use audio driver: one of jack, alsa, portaudio, pulse

-b | --bitrate bitrate
    Set MP3 output bitrate in kbit/s

-c | --config-folder pathname
    Override configuration and settings directory

-D | --monitor-resolution DPI
    Specify monitor resolution (override autodetection)

-d | --debug
    Start MuseScore in debug mode

-E | --install-extension extension file
    Install an extension file; soundfonts are loaded by default unless -e is also specified

-e | --experimental
    Enable experimental features, such as layers

-F | --factory-settings
    Revert all settings, shortcuts, workspaces, extensions, translations, etc. to factory defaults; compare with the -R option

-f | --force
    Ignore score corruption and version mismatch warnings in “converter mode”

-h | --help
    Display an overview of invocation instructions

-I | --dump-midi-in
    Display all MIDI input on the console

-i | --load-icons
    Load icons from the filesystem; useful if you want to edit the MuseScore icons and preview the changes

-j | --job file.json
    Process a conversion job (see EXAMPLES below)

-L | --layout-debug
    Start MuseScore in layout debug mode

-M | --midi-operations file
    Specify MIDI import operations file (see EXAMPLES below)

-m | --no-midi
    Disable MIDI input

-n | --new-score
    Start with the New Score wizard regardless whether it's enabled or disabled in the user preferences

-O | --dump-midi-out
    Display all MIDI output on the console

-o | --export-to file
    Export the given (or currently opened) file to the specified output file. The file type depends on the extension of the filename given. This option switches to “converter mode” and avoids the graphical user interface.

-P | --export-score-parts
    When converting to PDF with the -o option, append each part's pages to the created PDF file. If the score has no parts, all default parts will temporarily be generated automatically.

-p | --plugin name
    Execute the named plugin

-R | --revert-settings
    Revert user preferences to factory default but retain shortcuts, workspaces, extensions, translations, etc.; compare with -F.

-r | --image-resolution DPI
    Set image resolution for conversion to PNG files.

    Default: 300 DPI (actually, the value of “Resolution” of the PNG option group in the Export tab of the preferences)

-S | --style style
    Load a style file first; useful for use with the -o option

-s | --no-synthesizer
    Disable the integrated software synthesiser

-T | --trim-image margin
    Trim exported PNG and SVG images to remove whitespace surrounding the score. The specified margin, in pixels, will be retained (use 0 for a tightly cropped image). When exporting to SVG, this option only works with single-page scores.

-t | --test-mode
    Set test mode flag for all files

-v | --version
    Display the name and version of the application without starting the graphical user interface

-w | --no-webview
    Disable the web view component in the Start Centre

-x | --gui-scaling factor
    Scale the score display and other GUI elements by the specified factor; intended for use with high-resolution displays

--diff
    Print a conditioned diff between the given scores

--long-version
    Display the full name, version and git revision of the application without starting the graphical user interface

--no-fallback-font
    Don't use Bravura as fallback musical font

--raw-diff
    Print a raw diff between the given scores

--run-test-script
    Run script tests listed in the command line arguments

--score-media
    Export all media (except MP3) for a given score as a single JSON document to stdout

--score-mp3
    Generates an MP3 for the given score and exports it as a single JSON document to stdout

--score-parts-pdf
    Generates parts data for the given score and exports it as a single JSON document to stdout

--template-mode
    Save files in template mode (e.g. without page sizes)

MuseScore supports the automatic Qt command line options (see below).

  Batch conversion job JSON format
The argument to the -j option must be the pathname of a file comprised of a valid JSON document honouring the following specification:

•   The top-level element must be a JSONArray, which may be empty.

•   Each array element must be a JSONObject with the following keys:

    in  Value is the name of the input file (score to convert), as JSONString.

    plugin
        Value is the filename of a plugin (with the .qml extension), which will be read from either the global or per-user plugin path and executed before the conversion output happens, as JSONString. Optional, but at least one of plugin and out must be given.

    out Value is the conversion output target, as defined below. Optional, but at least one of plugin and out must be given.

•   The conversion output target may be a filename (with extension, which decided the format to convert to), as JSONString.

•   The conversion output target may be a JSONArray of filenames as JSONString, as above, which will cause the score to be written to multiple output files (in multiple output formats) sequentially, without being closed, re-opened and re-processed in between.

•   If the conversion output target is a JSONArray, one or more of its elements may also be, each, a JSONArray of two JSONStrings (called first and second half in the following description). This will cause part extraction: for each such two-tuple, all extant parts of the score will be saved individually, with filenames being composed by concatenating the first half, the name (title) of the part, and the second half. The resulting string must be a valid filename (with extension, determining the output format). If a score has no parts (excerpts) defined, this will be silently ignored without error.

•   Valid file extensions for output are:

    flac
        Free Lossless Audio Codec (compressed audio)

    metajson
        various score metadata (JSON)

    mid standard MIDI file

    mlog
        internal file sanity check log (JSON)

    mp3 MPEG Layer III (lossy compressed audio)

    mpos
        measure positions (XML)

    mscx
        uncompressed MuseScore file

    mscz
        compressed MuseScore file

    musicxml
        uncompressed MusicXML file

    mxl compressed MusicXML file

    ogg OGG Vorbis (lossy compressed audio)

    pdf portable document file (print)

    png portable network graphics (image)

        Individual files, one per score page, with a hyphen-minus followed by the page number placed before the file extension, will be generated.

    spos
        segment positions (XML)

    svg scalable vector graphics (image)

    wav RIFF Waveform (uncompressed audio)

    xml uncompressed MusicXML file

See below for an example.

ENVIRONMENT

SKIP_LIBJACK
    Set this (the value does not matter) to skip initialisation of the JACK Audio Connection Kit library, in case it causes trouble.

XDG_CONFIG_HOME
    User configuration location; defaults to ~/.config if unset.

XDG_DATA_HOME
    User data location; defaults to ~/.local/share if unset.

XDG_DOCUMENTS_DIR
    Location of works the user created with the application; defaults to ~/Documents (or a localised version) and can be set in $XDG_CONFIG_HOME/user-dirs.dirs.

Note that MuseScore also supports the normal Qt environment variables such as QT_QPA_GENERIC_PLUGINS, QT_QPA_PLATFORM, QT_QPA_PLATFORMTHEME, QT_QPA_PLATFORM_PLUGIN_PATH, QT_STYLE_OVERRIDE, DISPLAY, etc.

FILES
/usr/share/mscore-3.4/ contains the application support data (demos, instruments, localisation, system-wide plugins, soundfonts, styles, chords, templates and wallpapers). In the Debian packages, system-wide soundfonts are installed into /usr/share/sounds/sf2/, /usr/share/sounds/sf3/ or /usr/share/sounds/sfz/, respectively, instead.

The per-user data (extensions, plugins, soundfonts, styles, templates) and files (images, scores) are normally installed into subdirectories under $XDG_DOCUMENTS_DIR/MuseScore3/ but may be changed in the configuration. Note that snapshot, alpha and beta versions use MuseScore3Development instead of MuseScore3 in all of these paths.

$XDG_CONFIG_HOME/MuseScore/MuseScore3.ini contains the user preferences, list of recently used files and their locations, window sizes and positions, etc. See above for development version paths.

$XDG_DATA_HOME/MuseScore/MuseScore3/ contains updated localisation files downloaded from within the program, plugin information, cached scores, credentials for the musescore.com community site, session information, synthesiser settings, custom key and time signatures and shortcuts. See above for development version paths.

EXAMPLES
Convert a score to PDF from the command line:

    mscore -o 'My Score.pdf' 'My Score.mscz'

Run a batch job converting multiple documents:

    mscore -j job.json

This requires the file job.json in the current working directory to have content similar to the following:

    [
      {
        "in": "Reunion.mscz",
        "out": "Reunion-coloured.pdf",
        "plugin": "colornotes.qml"
      },
      {
        "in": "Reunion.mscz",
        "out": [
          "Reunion.pdf",
          [ "Reunion (part for ", ").pdf" ],
          "Reunion.musicxml",
          "Reunion.mid"
        ]
      },
      {
        "in": "Piece with excerpts.mscz",
        "out": [
          "Piece with excerpts (Partitura).pdf",
          [ "Piece with excerpts (part for ", ").pdf" ],
          "Piece with excerpts.mid"
        ]
      }
    ]

The last part of the job would, for example, cause files like “Piece with excerpts (part for Violin).pdf” to be generated alongside the conductor's partitura and a MIDI file with the full orchestra sound, whereas the equivalent part of the Reunion conversion will be silently ignored (because the Reunion piece (a MuseScore demo) has no excerpts defined).

https://musescore.org/sites/musescore.org/files/midi_import_options_0.xml is a sample MIDI import operations file for the -M option.

STANDARDS
MuseScore attempts to implement the following standards:

•   MusicXML 3.1 (score interchange format)

•   SF2 (SoundFont 2.01)

•   SF3 (SoundFont with OGG Vorbis-compressed samples)

•   SFZ (Sforzato soundfont)

•   SMuFL (Standard Music Font Layout 1.20)

HISTORY
MuseScore was split off the MusE sequencer in 2002 and has since become the foremost Open Source notation software.

AUTHORS
MuseScore is developed by Werner Schweer and others.

This manual page was written by mirabilos <tg@debian.org>.

CAVEATS
The automatic Qt command line options are removed from the argument vector before the application has a chance at option processing; this means that an invocation like

    mscore -S -reverse

has no chance at working because the -reverse is removed by Qt first.

BUGS
MuseScore does not honour /etc/papersize.

Probably some more; check the project's bug tracker (cf. SEE ALSO).
