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.

Changes:
This release enhances Strasheela's capabilities for outputting microtonal music into sound synthesis formats such as Csound or MIDI. The actual playback pitch of notes can be defined by tuning tables, which are similar to the scale format of Scala. New examples demonstrate different approaches for creating MIDI files for microtonal music.
