Strasheela

This release fixes a serious bug. Previously, Strasheela only worked when IOzSeF (an Oz extension for constraint solvers) was installed. It simplifies the installation on Windows by providing an installation batch file. It also adds a collection of ready-made constructors for musical segments such as contrapuntal lines, homophonic chord progressions, or specific motifs, and adds a number of harmony-related constraints. Further additions and bugfixes have been made as well.

This release brings many small-scale improvements and extensions to Strasheela. Most importantly, the implementation of Schoenberg's Theory of Harmony as CSP has been documented (HTML with sound examples), Strasheela now supports adaptive just intonation, the music representation has been extended by several convenient constructors, and a number of pattern constraints have been added. Also, some bugs have been fixed.

This release fixes a serious bug which even caused
a compilation error. In order to avoid such errors
in the future, the code has been cleaned up, and
virtually all compiler warnings are now fixed as
well. In addition, the tutorial revision
continued, and some distribution strategies have
been optimized.

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

This release supports new techniques for constraining the musical form, and demonstrates them in examples. Also, the definition of complex distribution strategies (variable orderings in the search) is simplified by special constructor functions. Several further examples have been added, and many other extensions and bugfixes have been made.
