Welcome to the Music Processing Suite Website!

Music Processing Suite (MPS) is a software system for advanced symbolic music processing with the following features:

Music Modeling

MPS is based on music models containing individual representations of musical aspects and contexts such as meter, tempo, rhythms, pitches, scales, harmonies, loudness, lyrics and more.

Music Analysis

Analysis infrastructure for statistical music analysis and visualization. MPS generates PDF reports containing statistical diagrams, tables, graphs and Markov models.

more

Composition Language

Composition language for intuitive, redundancy-free music specification and notation. Easily create your own scores and lead sheets.

more

Music Search

Advanced context-sensitive music search functionality

more

Transformations

Transformation infrastructure for conversions between various music representation formats such as MPS Models, MIDI, MusicXML, LilyPond, PDF, CSV, SuperCollider and more.

Starting MPS on Mac OS X Catalina

Posted on by

Multiple users reported issues when starting MPS on Mac OS X Catalina. The following error message is displayed:

MPS is damaged and can't be opened. You should move it to the Trash.

The reason for this error message is that MPS is not signed by an Apple-certified developer. To start it anyway, make sure you move MPS.app to your Applications folder (where most of your other programs are installed). Then open Terminal (e.g. by typing Terminal in spotlight) and copy and paste the following command:

sudo xattr -rd com.apple.quarantine /Applications/MPS.app

You will be asked to type it your password. Note that typed characters will not be displayed for security reasons. Afterwards, MPS should start. More detailed instructions can be found on the Downloads page, including hints how the problem can be solved for previous Mac OS X versions.

Release of Music Processing Suite 1.7.0

Posted on by

Music Processing Suite 1.7.0 was released on July 11, 2020.

New Features and Enhancements:

  • Updated Eclipse platform to version 2020-06 (4.16)
  • Implemented new MusicXML 3.1 model and parser based on the Eclipse Modeling Framework (EMF). It is still in an experimental state and can be activated in the MPS preferences.
  • Enhanced order in which keys are displayed in analysis overview tables
  • Analysis output files are now refreshed/displayed already before graph PDFs are generated, so they can already be browsed before PDF generation is finished

Bugfixes:

  • Fixed an issue when comparing rare harmonies (e.g. Bbb) according to their circle of fifths position
  • MusicXML-related options were not properly set when running composition crossovers and folder-based music analysis. Options are now passed properly.
  • Fixed a bug which caused note references not to be resolved in the default (western) tonal system instance

Release of Music Processing Suite 1.6.1

Posted on by

Music Processing Suite 1.6.1 was released on February 29, 2020.

New Features and Enhancements:

  • Added new analysis features for pitch combination analysis
  • Enhancements for Analysis Reports:
    • Added separate Harmony and Implicit Harmony progression plots over time
    • Overview plot now contains implicit (derived) harmony progressions
    • New plot for interval leap distribution over time
    • Enhanced dissonance over time plot
    • New tables containing pitch combination data
    • Added option to limit number of table rows in analysis reports
  • Improved launch configuration handling

Bugfixes:

  • Aligned times in time-dependent analysis data files (some started at t=1, now all start at t=0)
  • Fixed bug which caused fractions and tuples not to be exported as floating point numbers in CSV files
  • Fixed toolbar button for composition crossover

Release of Music Processing Suite 1.6.0

Posted on by

Music Processing Suite 1.6.0 was released on November 20, 2019.

New Features and Enhancements:

  • Updated Eclipse platform to version 2019-09 (4.13)
  • Enhanced generated LilyPond markup: MPS now inserts barlines and line breaks after each measure.
  • Analysis Result View can now be opened using the context menu when right-clicking an analysis folder (i.e. a folder ending with _Analysis).

Bugfixes:

  • All file write operations are foreced to use UTF-8 as encoding (before the system’s default encoding was used which lead to issues on Windows because the default encoding is not UTF-8).
  • Fixed inconsistencies in SVG library (Batik) dependencies
  • Fixed problem when notes contained in chords were tied to the corresponding notes in the next chord
  • Analysis Reports: Legends of overview plots do not overflow pages anymore
  • Analysis Reports: Missing lines are now visible in harmonic overview plot
  • Analysis Reports: Integers are not rendered as floating point numbers anymore
  • Analysis UI: Fixed transparency for 3D plots in analysis result view
  • Added missing command associations with the MPS category
