Release of Music Processing Suite 1.15.0

Posted on 6th January 20258th January 2025 by dave

Music Processing Suite 1.15.0 was released on January 6, 2025.

New Features and Enhancements:

Updated Eclipse base platform to version 2024-12
MPS is now able to compute the importance, also referred to as “indispensability”, of all note onsets/beats in all measures of a piece, respecting the metric context. The algorithm was proposed by Clarence Barlow. Two new analysis features are available:
- Indispensability over Time: indispensabilities of all note onsets over time (absolute time or measures)
- Indispensability Distribution: absolute or relative distribution of indispensability values
Significant performance improvements when writing or reading context layer models
Support for new Homebrew path /opt/homebrew/bin on Apple Silicon Macs, which allows to auto-detect external applications like GraphViz

Bugfixes:

Fixed incorrect beat and measure fraction calculations in upbeats
Fixed a NullPointerException when merging scale analysis data for multiple files when no scale analysis data was available for at least one file
Fixed a problem related to the Eclipse 2024-12 update that caused the CoreNLP server not to be startable (previous MPS versions were not affected)

Documentation:

List of analysis features was updated
Documentation for automatic detection of external libraries such as MuseScore and LaTeX was updated to contain all current built-in search paths

Release of Music Processing Suite 1.14.0

Posted on 8th February 20248th February 2024 by dave

Music Processing Suite 1.14.0 was released on February 8, 2024.

New Features and Enhancements:

Updated Eclipse base platform to version 2023-12
MuseScore 4 is now detected automatically as score generation application
Tempo specifications are now added to generated scores by default
Added analysis feature for scale conformity in the scope of the whole piece. The algorithm computes the semitone distance of all pitches to the context harmony root note and the key root note. At the end the conformity of all built-in scales is computed as a percentage value.

Bugfixes:

MusicXML Processing:
- When playing back generated MusicXML files, instrument sounds were not correct in all cases. A new attribute for instrument definitions was introduced that allows to specify the MusicXML instrument sound as specified in the MusicXML specification. The MPS instrument library was enhanced where applicable.
Composition Editor:
- In case a score was generated for a composition file which was not saved yet, a dialog appeared asking whether the file should be saved. However, the old version was still used. This issue has been fixed.

Music Processing Suite 1.13.0 was released on April 8, 2023.

Note: since version 1.11.0, MPS requires Java 17 to run. It is recommended to download a Java 17 JDK for your operating system from Zulu.

New Features and Enhancements:

Updated Eclipse base platform to version 2023-03
Added experimental feature to compute correlations between musical parameters. The following correlations are computed if corresponding data is available:
- Loudness vs. Dissonance
- Loudness vs. Sentiment Polarity
- Dissonance vs. Sentiment Polarity

Bugfixes:

MusicXML Processing:
- Minor seventh (m7) chords are now correctly exported to MusicXML
- Fixed export of lyric syllables that are extended across multiple notes
- Fixed issue where lyric syllables were repeated if notes were divided (e.g. across a bar line)
- Previously it was not possible to tie more than two notes rhythmically when exporting to MusicXML. This issue has been fixed.
Miscellaneous Fixes:
- Fixed a NullPointerException during automatic detection of external applications that occurred on Windows systems in case of insufficient file system permissions
- Fixed an IndexOutOfBoundsException when generating scores with the fret board diagram option disabled and no fret board instrument selected

Music Processing Suite 1.12.0 was released on August 26, 2022.

Note: since version 1.11.0, MPS requires Java 17 to run. It is recommended to download a Java 17 JDK for your operating system from Zulu.

New Features and Enhancements:

Bugfixes:

MusicXML Processing:
- Fixed NullPointerException that occurred if MusicXML files did not contain an identification element
- Fixed NullPointerException that occurred if MIDI instrument definitions did not contain certain elements such as midiProgram
- Fixed an issue that resulted in incorrect context layer model representations if rests were modeled as chords
