pyo is a Python module written in C to help digital signal processing script creation. pyo is a Python module containing classes for a wide variety of audio signal processing types. With pyo, user will be able to include signal processing chains directly in Python scripts or projects, and to manipulate them in real time through the interpreter. Tools in pyo module offer primitives, like mathematical operations on audio signal, basic signal processing (filters, delays, synthesis generators, etc.), but also complex algorithms to create sound granulation and others creative audio manipulations. pyo supports OSC protocol (Open Sound Control), to ease communications between softwares, and MIDI protocol, for generating sound events and controlling process parameters. pyo allows creation of sophisticated signal processing chains with all the benefits of a mature, and wildly used, general programming language. Systems : OS X (10.5, 10.6, 10.7), linux, Windows (XP, Vista, Seven)

PortMedia is a set of APIs and library implementations for music and other media. PortMedia is open-source and runs on Windows, Macintosh, and Linux. Currently, libraries support Audio I/O and MIDI I/O.

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 MIDI module provides MIDI input parsers for Python.
