Hey all! I've packaged a really nice MIDI debug tool: https://github.com/NixOS/nixpkgs/pull/277901

If anyone have a macOS on hand and can make the macOS port, or have time to review the PR, I'd appreciate it!

So I used musnix to set everything up:

  sound.enable = false;
  hardware.pulseaudio.enable = false;
  security.rtkit.enable = true;
