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)
[144, 60, 64]
<message note_on channel=2 note=60 velocity=64 time=0>
with mido.open_input('LinnStrument') as inport:
for msg in inport:
port = mido.open_output()
mid = mido.MidiFile('song.mid')
for msg in mid.play():

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