How to cross-compile with a custom stdenv on Nix
{
outputs = { nixpkgs, ... }: {
pkgsWeb = import nixpkgs {
system = "x86_64-linux";
# NOTE: enabling setting crossSystem disables config.replaceStdenv
crossSystem = {
config = "wasm32-unknown-none";
rust.rustcTarget = "wasm32-unknown-unknown";
useLLVM = true;
};

Where:

  • r = reference
  • n = number
  • i = integer
  • c = compound_notes, note can be midi number, rest _, or compound note such as _60
  • s = symbol

Signals

imp frequency:n - impulse signal, it can be used as a trigger to a sampler or sawsynth
