Haskore is a set of Haskell modules for creating music as MIDI, CSound, and Audio files.
There is a darcs repo, not apparantly mentioned on that page, at http://cvs.haskell.org/darcs/haskore/.
A lot of projects were initiated that use the Haskore framework or something in the spirit of Haskore. This Wiki may help to keep an overview of all projects. All maintainers of Haskore related projects are encouraged to add their project here and keep the references up to date.

You feed the program with a chord chart, set the desired style (jazz, bossa, etc.), tempo, key etc. and it produces a simple MIDI file containing an according bass and drum track. Includes a lot of examples. || || Design experiments || Henning Thielemann ||  || Test of several changes of Haskore's design targetting at more flexibility and consistency || || EDSL || John Peterson || ,  || Educational Domain Specific Languages || || Emile || Adam Bermingham ||  || Eight-Bar Melody Generation in Haskell.
