• Started documentation for the project (in progress)

0.8.0 - Paper Release

This release is related to the first version of the project published with the paper.
There are some minor changes in behavior w.r.t. the published version and the currently published dataset. Therefore, this release breaks compatibility with the results obtained in the paper. Nevertheless, the original dataset will be kept public for scientific purposes.

New features

• Tests were added for specific aspects of the notation.
• Added start-of-measure and end-of-measure barlines for deambiguation. Inserted regular barlines by default whenever MusicXML omits them for simplicity to reinforce the idea that visual tokens are always explicit in the notation.
• Added a visitor for a sequence-based format for scores.

Bugfixes

• Fixed a bug where note-groups were not simplified properly when nested further than 1 level.
• Fixed a bug where attributes would always be inserted at the beginning regardless of their delta.
• Fixed a bug where attributes would not be merged when having the same delta.
• Fixed a bug where noteheads of types other than default were not generated.
• Fixed a bug where attributes were not taken into account for those situations where the attribute change is denoted after the notes are processed in the MusicXML file.
