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)
