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 contexts such as meter, tempo, rhythms, pitches, scales, hierarchical harmonic relations, loudness, lyrics and more.

more

Composition Language

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

more

Powerful IDE

MPS is a powerful customizable application based on Eclipse

more

Transformations

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

more

Music Search

Advanced context-sensitive music search functionality

more

Music Analysis

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

News and Updates

Latest Posts

Release of Music Processing Suite 1.2.2

Music Processing Suite 1.2.2 was released on February 26, 2019.

New Features and Enhancements:

  • The music model now supports two independent scale degree layers: degrees relative to the key and degrees relative to the local harmony.

Bugfixes:

  • Updated dependencies in order to populate MPS update site properly

Release of Music Processing Suite 1.2.1

Music Processing Suite 1.2.1 was released on February 22, 2019.

New Features and Enhancements:

  • Analysis reports now contain tables with relative frequencies of words and syllables used in the lyrics of the analyzed piece

Bugfixes:

  • Pitches with more than one accidental (e.g. Bbb, Ebb, Abb) are now correctly serialized to LilyPond
  • Improved handling of empty compositions
  • Repeats are now correctly expanded in MusicXML (if corresponding expand option is activated in the preferences)
  • Improved robustness of MusicXML parser if (erroneous) files initiate a word with a syllable marked as MIDDLE instead of BEGIN
  • Fixed rendering of upbeats when converting MusicXML files to scores

Music Processing Suite Development Visualization

The following video visualizes the development of MPS from June 2013 to December 2018. I presented it at my PhD disputation and since it is quite entertaining, I decided to share it on the website as well. Enjoy, merry christmas and all the best for 2019 🙂

Release of Music Processing Suite 1.2.0

Music Processing Suite 1.2.0 was released on October 26, 2018.

New Features and Enhancements:

  • Updated underlying Eclipse platform to 4.7 (Oxygen)
  • Optimized model compression algorithm in deriver
  • Derived models now contain time signatures, intrument contexts and keys
  • Added algorithm which derives scale degrees relative to the key
  • Added option to enable degrees relative to the key
  • Added configuration parameter for context layer model scaling
  • Added documentation for visualization options
  • Improved path presentations is search result view
  • Improved piano roll plots in analysis reports
  • Columns in aggregated plots are now sorted in analysis reports
  • Added support for half-diminished and diminished seventh chords
  • Improved colors in 3D plots
  • Made documentation and user interface consistent regarding the term “context layer model”
  • Documentation now has table of contents
  • MPS now includes the Eclipse Marketplace Client

Bugfixes:

  • Resolved bugs when resolving fragment references with additional child nodes
  • Fixed ClassCastException that occurred when deriving compressed rhythm representations contained in modifiers
  • Fixed bug resulting in inconsistent tempo specifications when reading MIDI files
  • Fixed inconsistent measure boundaries which occurred when voice begins with rest
  • Fixed issue in which measures with the same boundaries were created twice
  • Fixed TeX capacity exceeded error when generating analysis reports
  • Fixed unicode handling in analysis reports
  • Empty circle of fifth plots in analysis reports are now skipped
  • Fixed export of missing key-related data during analysis
  • Analysis log files are now created correctly (were empty sometimes)
  • Fixed LilyPond export for maj9 chords
  • Octave translation problem when using pitch modifiers was solved
  • Fixed octave translation problem for transposed instruments
  • Tied notes are exported correctly now
  • Fixed problem regarding quotes in metadata fields (such as title, composer etc.)
  • Lyric syllables are now handled correctly after tied notes
  • Harmony stream is only filled if harmonies are explicitly specified
  • Prevent NullPointerException if score geneneration is launched but file does not exist anymore
  • Fixed loudness handling for chords when exporting scores
