Parameters
----------
directory, key, index, file_re, folder_re, exclude_re, recursive : optional
Arguments for the method :py:meth:`~ms3.parse.add_folder`.
If ``dir`` is not passed, no files are added to the new object except if you pass ``paths``
paths : :obj:`~collections.abc.Collection` or :obj:`str`, optional
List of file paths you want to add. If ``dir`` is also passed, all files will be combined in the same object.
WARNING: If you want to use a custom index, don't use both arguments simultaneously.
index : element or :obj:`~collections.abc.Collection` of {'key', 'i', :obj:`~collections.abc.Collection`, 'full_paths', 'rel_paths', 'scan_paths', 'paths', 'files', 'fnames', 'fexts'}
| Change this parameter if you want to create particular indices for output DataFrames.
| The resulting index must be unique (for identification) and have as many elements as added files.
| Every single element or Collection of elements ∈
{'key', 'i', :obj:`~collections.abc.Collection`, 'full_paths', 'rel_paths', 'scan_paths', 'paths', 'files', 'fnames', 'fexts'}
stands for an index level in the :obj:`~pandas.core.indexes.multi.MultiIndex`.
| If you pass a Collection that does not start with one of the defined keywords, it is interpreted as an
index level itself and needs to have at least as many elements as the number of added files.
| The default ``None`` is equivalent to passing ``(key, i)``, i.e. a MultiIndex of IDs which is always unique.
| The keywords correspond to the dictionaries of Parse object that contain the constituents of the file paths.
simulate : :obj:`bool`, optional
Pass True if no parsing is actually to be done.
logger_cfg : :obj:`dict`, optional
| The following options are available:
| 'name': LOGGER_NAME -> by default the logger name is based on the parsed file(s)
| 'level': {'W', 'D', 'I', 'E', 'C', 'WARNING', 'DEBUG', 'INFO', 'ERROR', 'CRITICAL'}
| 'path': Directory in which log files are stored. If 'file' is relative, this path is used as root, otherwise, it is ignored.
| 'file': PATH_TO_LOGFILE Pass absolute path to store all log messages in a single log file.
If PATH_TO_LOGFILE is relative, multiple log files are created dynamically, relative to the original MSCX files' paths.
If 'path' is set, the corresponding subdirectory structure is created there.
ms : :obj:`str`, optional
If you want to parse musicXML files or MuseScore 2 files by temporarily converting them, pass the path or command
of your local MuseScore 3 installation. If you're using the standard path, you may try 'auto', or 'win' for
Windows, 'mac' for MacOS, or 'mscore' for Linux.

unfold : bool, optional
By default, repetitions are not unfolded. Pass True to duplicate values so that they correspond to a full
playthrough, including correct positioning of first and second endings.
quarterbeats : bool, optional
By default, no ``quarterbeats`` column is added with distances from the piece's beginning measured in quarter notes.
Pass True to add the columns ``quarterbeats`` and ``durations_quarterbeats``. If a score has first and second endings,
the behaviour depends on ``unfold``: If False, repetitions are not unfolded and only last endings are included in the
continuous count. If repetitions are being unfolded, all endings are taken into account.
