I attended the Workshop in Algorithmic Composition in 2005, where
David Cope is one of the teachers and organizers. It was all in all a
very useful course, and some well spent 10 days. Cope did explain some
things about EMMY (his software) during the course, revealing that it
is all basically Markov based. I do not recall that he went into
details about the analysis part (i.e. the pattern matching), but I
recall that he expling about how the database was made, and that he
did a lot of hand editing on the database to optimize the output (the
music made by the software).
I do not think his software is available online in a complete form,
but you might get snippets of code here and there (not sure).
To get more insight on this, (and other algorithmic composition
issues) I would higly recommend attending the summer course. I think
they are still admitting students for this year's course. Search for
WACM, Cope, UC Santa Cruz and I think you'll find it easily.
