Nudruz -- A collection of Common Music routines
This is a bunch of functions and processes developed for the ... awesome ... Common Music system, including tonnetz implementations, nondeterministic programming, tiling canons, and other stuff. I've also thrown in some Lisp 'sketchbooks' from some recent compositions.

MIDIFilt -- Filtering and manipulating midi files
These 12 perl scripts use the MIDI::Perl module to let you manipulate MIDI files from the command-line. Written in Perl; requires a perl interpreter and the MIDI::Perl module.
PerlCans -- Canon-generating and melody scripts
These scripts include canons of different flavors and rules -- they tell you which canons of a melody (which mensuration and interval) will pass your own home-made criteria. There are also some pitch-set and rotation thingies. Requires a perl interpreter.
