jack_midi_keyboard

Provides a comfy interface to python from a MIDI keyboard via JACK.

Running from the command line will simply demonstrate its usage, printing out the notes played on the first physical MIDI input found:

python -m jack_midi_keyboard

An example of using this package:

from jack_midi_keyboard import JackMidiKeyboard

def note_on(channel, pitch, velocity, *_):
	print(f' {channel:02d}  {pitch:02d}  {velocity:02d}')

def note_off(channel, pitch, *_):
	print(f' {channel:02d}  {pitch:02d}')

with JackMidiKeyboard(auto_connect = True) as kbd:
	kbd.on_note_on(note_on)
	kbd.on_note_off(note_off)
	input()	# Causes execution to wait for user input

You can also extend the JackMidiKeyboard class with your own class.

Versatility

Although this package is named "jack_midi_keyboard", this class can be used to receive MIDI events from any kind of Jack MIDI output port, software or hardware.
