nix run github:TheCodedKid/des-pas

# flake.nix
inputs.des-pas.url = "github:TheCodedKid/des-pas";

# configuration
imports = [ des-pas.nixosModules.default ];

services.desPas = {
  enable   = true;
  duration = 4;
  code     = ''
    setcps (1/2)
    d1 $ n "0 4 7 11" # sound "supersaw" # gain 0.7 # release 0.5

};

Requires services.pipewire.jack.enable = true.

"des pas" in French means "footsteps". I naming comes from "Des pas sur la neige" from Claude Debussy, which means "footsteps in the snow", which is a classical piece I enjoying listening too.
