mido 1.2.0

MIDI Objects for Python

Mido is a library for working with MIDI messages and ports. It’s designed to be as straight forward and Pythonic as possible:

>>> import mido
>>> msg = mido.Message('note_on', note=60)
>>> msg.note
60
>>> msg.bytes()
[144, 60, 64]
>>> msg.copy(channel=2)
<message note_on channel=2 note=60 velocity=64 time=0>

with mido.open_input('LinnStrument') as inport:
    for msg in inport:
        print(msg)

port = mido.open_output()
port.send(msg)

mid = mido.MidiFile('song.mid')
for msg in mid.play():
    port.send(msg)

Main Features

• works in Python 2 and 3.

• convenient message objects.

• supports RtMidi, PortMidi and Pygame. New backends are easy to write.

• full support for all 18 messages defined by the MIDI standard.

• standard port API allows all kinds of input and output ports to be used interchangeably. New port types can be written by subclassing and overriding a few methods.

• includes a reusable MIDI parser.

• full support for MIDI files (read, write, create and play) with complete access to every message in the file, including all common meta messages.

• can read and write SYX files (binary and plain text).

• implements (somewhat experimental) MIDI over TCP/IP with socket ports. This allows for example wireless MIDI between two computers.

• includes programs for playing MIDI files, listing ports and serving and forwarding ports over a network.
