Audio related things I've written include python
bindings for the
jack dbus interface, a jack application managing tool to
start/stop/mute applications via hardware buttons
My 7-key SpiderIsland (USB keyboard interface, not MIDI) just came,
and I'm planning to set it up with XFCE keyboard shortcuts to command
non-mixer to do mutes and volume changes, of audio channels in my BNR
(
https://github.com/ponderworthy/the-box-of-no-return-3 ).
I have an example for python-rtmidi, which does a similar thing, i.e.
you can run arbitrary commands on reception of certain MIDI events.
You can combine this with e.g. "xdotool" to send keyboard strokes to
applications.

IIRC, non-mixer has an OSC interface, so the more direct way would be
to use a MIDI-to-OSC gateway. I have an example for that using
python-rtmidi as well
https://github.com/SpotlightKid/osc2rtmidi
... but these days I would recommend just using midimonster, which is
very powerful and an active project:

Dear Lord, midimonster is quite a monster. Looks like a very good tool
when you need it. I like your method better; simpler. I'm using a
different Python OSC library and non-midi keyboard control so I can run
with any MIDI musical keyboard easily, I don't have to sort out MIDI
events beyond the universal notes and sustain. So the simplest test is:
1. User hits keyboard key, starts a shortcut via distro desktop
2. Shortcut starts the following applet, which talks to non-mixer
using OSC, and tells it to mute the appropriate channel.
import argparse
import random
import time
from pythonosc import udp_client
if __name__ == "__main__":
parser = argparse.ArgumentParser()
parser.add_argument("--ip", default="127.0.0.1",
help="The ip of the OSC server")
parser.add_argument("--port", type=int, default=7587,
help="The port the OSC server is listening on")
args = parser.parse_args()
client = udp_client.SimpleUDPClient(args.ip, args.port)
client.send_message("/strip/DistortionOutput/Gain/Mute", 1.0)
