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.

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.

Powerful IDE

MPS is a powerful customizable application based on Eclipse

Release of Music Processing Suite 1.2.0

Posted on by

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

Release of Music Processing Suite 1.1.0

Posted on by

Music Processing Suite 1.1.0 was released on April 8, 2018.

New Features:

  • Configuration for score generation is now managed for each input file individually in launch configurations
  • Improved support for chord symbols in MusicXML files
  • Score compiler automatically detects if two piano staves are used and produces a suitable piano staff layout
  • Added score generation option to omit instrument names at the left hand side of the staves
  • Added option to export analysis log files
  • Added option to export analysis results for each file when analyzing multiple compositions
  • Improved documentation and screenshots for configuring analysis, score generation, LaTeX and GraphViz

Bugfixes:

  • Fixed pitch resolution logics relative to harmonic context
  • Fixed serialization issues when writing to the same file more than once
  • Internal optimizations of harmony and key analysis, fixes a problem where harmonic progression data was not exported when performing global analysis
  • Fixed a bug in SuperCollider compiler which sometimes caused the tempo to become zero
  • Fixed NullPointerExceptions when evaluating configuration options
  • Fixed various Exceptions in analysis code in corner cases
  • Fixed NullArgumentException when analyzing lyrics which occurred if words are not terminated correctly in MusicXML files
  • Include MIDI files when scanning corpus contents recursively (before, only MusicXML files were taken into account)
  • Improved String representations of model elements, added missing information to harmony representations

Official Release of Music Processing Suite

Dear visitors,

the very first official version of Music Processing Suite was released today. Version 1.0.0 can now be downloaded from this website.

In the hope that the software will be useful for musicians and scientists, I am very curious to hear what you think about MPS and if you have any ideas, thoughts or suggestions. Please comment on the mailing list or write me a mail directly.

Best regards,
David
