@Minijackson:matrix.orgMinijacksonHey 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!12:00:37

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!
I'll definitely take a look at that once I get things sorted. Looks very interesting.

@wonko:4amlunch.netBrian HechingerBut, in the meantime I'm struggling big time with getting audio working properly.16:52:45
@wonko:4amlunch.netBrian Hechinger

So I used musnix to set everything up:

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

@wonko:4amlunch.netBrian HechingerRaySession (which I'd really like to use) claims that JACK isn't running.17:01:52
@wonko:4amlunch.netBrian HechingerIf I use qjackctl that sees jack as running and reports back all the info.17:02:48
@wonko:4amlunch.netBrian HechingerIf I use qjackctl or qpwgraph to do routing (attempting to route through ardour, for example) no audio ever gets anywhere even though the graph shows that it should.17:03:34
