Python MIDI Library

This is the library I built to easily write and read MIDI messages via Python.


When I decided to build my own midi foot-controller, I wanted to run it using Python.

As I looked for Python MIDI libraries, I didn't find anything that suited me, so I decided to program it myself. I published it in Python officials package, and all the code is open-source.


import midi
connector = midi.MidiConector('/dev/serial0') # the argument must match the path to serial port

# If you want to read MIDI message
message = connector.read() # return a Message type object

# You can then access several attribute of the message
t = message.type # could be ProgramChange, ControlChange, SysEx, NoteOn, ...
channel = message.channel # Midi channel on which the message has been received, from 1 to 16
first_byte = message.status # Value of the first byte (a Midi message is composed of 2 or 3 bytes)

# If you want to send MIDI messages
note = NoteOn(32, 127) # Note number 32 (G#) at max velocity
channel = 1 # You are about to send a message on MIDI channel 1
message = Message(note, channel)

connector.write(message) # will send the MIDI message NoteOn on channel #1

You can also send or receive in OMNI mode (ie on every channel at the same time). For further details, please have a look at the source code, or run

help(midi)

to read the docs.

As always, you are more than welcome to contact me if you have any feedback or suggestions.
