Virtual MIDI bus

There is currently no default MIDI bus name in the project. User will need to provide through the command line argument

Capturing multiple sound devices

spatialaudio/python-sounddevice#154

Run Commands

To see all command-line arguments:

poetry run python src/main.py -h

To see all devices and virtual MIDI buses that are available:

poetry run python src/main.py -l

A sample output on my machine:

Sound devices:
>  0 AirPods, Core Audio (1 in, 0 out)
   1 AirPods, Core Audio (0 in, 2 out)
   2 BlackHole 16ch, Core Audio (16 in, 16 out)
   3 BlackHole 2ch, Core Audio (2 in, 2 out)
   4 MacBook Pro Microphone, Core Audio (1 in, 0 out)
<  5 MacBook Pro Speakers, Core Audio (0 in, 2 out)
   6 ZoomAudioDevice, Core Audio (2 in, 2 out)
   7 in mac + B2 program, Core Audio (3 in, 2 out)
   8 in mac + B16 video, Core Audio (17 in, 16 out)
   9 out mac + B16 daw, Core Audio (0 in, 2 out)
  10 out mac + B2 video, Core Audio (0 in, 2 out)
Virtual MIDI Buses:
   0 IAC Driver Bus 0
   1 IAC Driver Bus 1

To run src/main.py with device 4 and bus 0:

poetry run python src/main.py -d 4 -u 0

Or to run multiple devices, for example, with device 0, device 4 and bus 0, bus 1:

poetry run python src/main.py -d 0 4 -u 0 1

The output of device 0 will then send to the bus 0, device 4 will send to bus 1
