MIDI-Perl
MIDI-Perl is a suite of Perl modules which allows MIDI files
to be read in and manipulated, or composed anew, and written out as
MIDI files.
Its simplest uses include listing text events from MIDI files for
archival purposes, making dumps of MIDI files for debugging purposes,
and extracting, saving, or dumping sysexes. More complex applications
include aleatoric/algorithmic composition, and modifying existing MIDI
files (e.g., changing their timing, transposing their key, or
performing some yet more complex transform on them).
The new MIDI::Simple module also provides a simple and concise
functional/procedural interface to most MIDI functionality.
Availability
You can get MIDI-Perl from
the MIDI directory
in CPAN. You can also
browse the MIDI-Perl docs there, too.

News

- Altho MIDI-Perl hasn't seen many new releases in the past
few years, it has seen a
lot of continued use. I get what I would call a steady trickle of messages
from people using it for one or another surprising use; and I myself
just used it to write the
Clock of the Long Now chimes
browser.
Moreover, there's now a lot of MIDI-related modules in CPAN.
Just
look!
- 02005-01-29
- Maintenance release: 0.81. Just some doc tweaks and a few more
dist-tests; no real changes in the actual code.
- 02000-08-21
- Bugfix version: 0.78. Fixes a bug in MIDI::Score that prematurely
ended notes in apparently rare circumstances. Thanks to Carl McTague
for leading me to discover the bug.

- MIDI-Perl 0.76 is out. Just lists my new email address, and fixes an
obscure bug in the
dump routines.
- 02000-03-06
- MIDI-Perl 0.75 is out -- just a bit more sanity checking in the MIDI/Opus.pm
file-reading routines. Minor internal optimizations to MIDI/Event.pm.
- 01999-05-13
- MIDI-Perl 0.74 is out -- no real functionality changes, just a few tweaks
so that people using -w (warnings) will see fewer complaints.
