Strasheela is a highly expressive constraint-based music composition system. Users declaratively state a music theory and the computer generates music which complies with this theory. A theory is formulated as a constraint satisfaction problem (CSP) by a set of rules (constraints) applied to a music representation in which some aspects are expressed by variables (unknowns). Music constraint programming is style-independent and is well-suited for highly complex theories (e.g. a fully-fledged theory of harmony). Results can be output into various formats including MIDI, Lilypond, and Csound.
Chaplin ACT is a Java class transformer which brings several modern language concepts into Java: contexts, composites, roles, traits (mixins), runtime type conversion, dynamic method signatures, method and field aggregators, etc. Using these concepts makes designing loosely-coupled applications and writing cohesive code easier. Chaplin can work either as a JVM agent or as a post-compilation class transformer. It does not introduce any new syntax. All functionality is implemented by means of the standard Java language elements.
Impro-Visor is a music notation and playback tool for helping jazz musicians learn to improvise. It features a notation GUI, automated playback of chords and rhythm using MIDI, and improvisation advice provided in a variety of ways, including being able to improvise jazz itself. Data are stored as open-format text files. MIDI and MusicXML export are also available.
Components 4 Java is a development tool for Java. It provides a framework to organize and separate different parts of code, and fills the gap between the class level and the library level as provided by the Java SE architecture. Additionally, you can organize your classes in well-separated and loosely coupled components. Those can be stuck together graphically into larger compositions. Finally, components and compositions will be distributed among Java archives as specified in assemblies.
Scorealgorithm1 composes musical scores using controlled, randomized procedures. It is written in Python, and the output is compatible with the digital synthesis software CSound. Scorealgorithm1 is a flexible composition tool that can create varied styles of music with changing harmonic, melodic, and rhythmic textures. The program also features various tuning systems and adaptable performance controls. Complex repetition, even canonic imitation, is possible. Visit the Web site for tutorials, documentation, and examples of music created using the software.
