scarlett_yaml

Script for dumping a Focusrite Scarlett's internal mixer configuration
to YAML, and loading it back again.

This is important on Linux for two reasons:

• one cannot run Focusrite's MixControl app (even under Wine or in a
  Windows VM)

• the configuration changes made via ALSA's amixer are not persisted
  to the interface's flash storage, which means the configuration is
  reset to the factory / last saved values on a power cycle.

Usage

Dump to standard output:

.. code-block: bash

$ python scarlett_yaml.py

Dump to a file

.. code-block: bash

$ python scarlett_yaml.py > my_config.yaml

Load from a file:

.. code-block: bash

$ python scarlett_yaml.py load my_config.yaml

TODOs

• Normalize command-line handling for the script (e.g., add an
  arg parser, support dumping to a file directly, support loading
  from standard input, etc.)

• Capture additional ALSA information (e.g., output gain channel names,
  parameter read-write / read-only status, etc.) See the output of
  amixer -cUSB contents.

• Extract the data model from the script into a separate, importable
  module.

• Write some kind of GUI? Probably YAGNI for me: the dumped YAML
  is enough for my usecases (I'd rather edit text than use the mouse
  to tweak hundreds of sliders / knobs, e.g. in qasmixer.
