Control PulseAudio with Novation Launch-Control MIDI Device by Python Script

This Script let's you control Pulseaudio sinks and input streams.

Feel free to Fork and Pull-Request your enhancements to this file!

Hint: This Script does not work right out of the box. you need to change your tuple lines to your need to make this work.

---

the script is ran by launch_control(tuple_list) Each tuple defines one knob.

This is the structure of a tuple:

(button_id, type, target, notification_title)

button_id

the id of the knob you want to control something

type

You can either control pulseaudio sinks or input_sinks, e.g. vlc media player sound or Discord or Firefox... this is defined by the type:

normal sink = "volume" input_sink = "input_volume"

target

if type == "volume":

look at the pulseaudio input_volume streams by typing:

pactl list sinks

get device.description of your output-device - this is your target-String (you might need to define yourself an output, e.g. by addin a line like this to ~/.config/pulse/default.pa)

  load-module module-remap-sink sink_name="Focusrite\ Solo\ Front" sink_properties="device.description='Focusrite\ Solo\ Front' " master=0 channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right remix=no

if type == "input_volume"

look at the pulseaudio input_volume streams by typing:

pactl list sink-inputs

get application.process.binary of your input_stream - this is your target-String

notification_title

The volume of your stream gets printed out to your notifications. notification_title defines the Title of this notification.
