As a quick followup, I found my Midi keyboard, and tried some things.
I had good luck with the `rtmidi` module:
https://pypi.python.org/pypi/python-rtmidi
It's pretty easy to open up a midi device, and create a callback for key
presses. Instead of using the "on_key_press" events in pyglet, you can use
the rtmidi callback to set the characters. You will need to determine what
the midi data actually means, and create some kind of mapping. A dictionary
will work well for that.
import time
import rtmidi
midi_in = rtmidi.MidiIn()
available_ports = midi_in.get_ports()
print(available_ports)
# I have a USB midi keyboard, and device #2 is the input:
port = midi_in.open_port(2)
def printer(message, data):
# Actually update something here
print(message, data)
port.set_callback(printer, data=None)
while True:
# Dumb event loop
time.sleep(1)
