Dear all,

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.

The output facilities to Lilypond are greatly revised in this
release. Strasheela now outputs the format of the latest stable
Lilypond release (2.10.0), supports various special cases (e.g.,
single staff polyphony, chords, enharmonic notation, basic tuplets),
and the customisation options have been extended. New examples
demonstrate these features. In addition, this version facilitates
composition in 22-tone equal temperament (22 ET): various 22 ET
chords and scales are provided, and output to Lilypond, as well as
Csound is supported. New examples have been added which create
microtonal chord progressions. Other additions and bugfixes have been
made to the system as well.
