Introduction

A CircuitPython helper for encoding/decoding MIDI packets over a MIDI or UART connection.

Dependencies

This driver depends on:

Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-midi

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-midi

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-midi

Usage Example

import time
import random
import usb_midi
import adafruit_midi

from adafruit_midi.note_on import NoteOn
from adafruit_midi.note_off import NoteOff
from adafruit_midi.pitch_bend import PitchBend
from adafruit_midi.control_change import ControlChange

midi = adafruit_midi.MIDI(midi_out=usb_midi.ports[1], out_channel=0)

print("Midi test")

print("Default output MIDI channel:", midi.out_channel + 1)

while True:
    midi.send(NoteOn(44, 120))  # G sharp 2nd octave
    time.sleep(0.25)
    a_pitch_bend = PitchBend(random.randint(0, 16383))
    midi.send(a_pitch_bend)
    time.sleep(0.25)
    midi.send([NoteOff("G#2", 120),
               ControlChange(3, 44)])
    time.sleep(0.5)
