Over the wire this morning I see that John Walker, sitting in his Mountain Stronghold in Switzerland, has released new versions of
csvmidi, a couple of nerdy Perl utilities that convert standard MIDI (musical composition) files to and from Comma-Separated Value (CSV) text files, which can easily be manipulated by programs to perform various transformations on musical works.
In other startling news, any two systems that can be modeled with whole numbers can also model each other.
Left as an exercise for the reader: write a song about MIDI. Submit your work as a CSV. (Come on, people, it's 2008. I can't believe this doesn't exist yet. Get cracking.)
