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.

This release improves Strasheela's export of sound synthesis
formats. For example, expressive timing of scores can be defined by
time shift functions. Predefined MIDI file export now supports also
non-note events like continuous controllers (e.g., pitch bend,
aftertouch, CC) and a global tempo curve. Additional examples have
been added, and further extensions and bug fixes have been made as
