	Source-available plugins can be packaged like any other library; note that the ~~output~~ files should ~~wind up~~ in <code>$out/lib/vst3</code>.		Source-available plugins can be packaged like any other library; note that the files should be in a subdirectory according to the plugin type e.g. <code>$out/lib/vst3</code>.

	If the plugin is only available as a binary, you may need to use [[Packaging/Binaries\|the advice on packaging binaries]] to help. Since many plugins will not be accessible via the standard fetchers, you can always fall back on including the plugin using <code>src = ./plugin.zip</code>; note that if you're using flakes and don't want to commit the plugin to Git (an especially bad idea if your config is public!), you can use requireFile and manually add files to the store. To do this, run <code>nix-hash --flat --type sha256 plugin.zip</code>, take the output, and use it in a derivation like so:		If the plugin is only available as a binary, you may need to use [[Packaging/Binaries\|the advice on packaging binaries]] to help.

[https://github.com/musnix/musnix Musnix] provides a set of simple, high-level configuration options for doing real-time audio work in NixOS, including optimizing the kernel, applying the CONFIG_PREEMPT_RT patch to it, and adjusting various low-level system settings, eg. setting up ulimit values automatically.

== VSTs ==

VSTs go in either ~/.vst or ~/.vst3If using VSTs, they may depend on libraries that are not available in the Renoise path. This will show up in the logs as an error along the lines of

Vst3Plugs: Failed to load module: dlopen failed.
libSM.so.6: cannot open shared object file: No such file or directory

To solve this, you'll need to turn Renoise into a wrapper that adds the missing libraries to the LD_LIBRARY_PATH:

<syntaxhighlight lang="nix">
let
vstLibs = with pkgs; [
# your libraries go here
];
renoiseWithVsts = with pkgs;
renoise.overrideAttrs (prev: {
nativeBuildInputs = [ makeWrapper ];
# keep the existing postFixup script as well
postFixup = prev.postFixup + ''
wrapProgram $out/bin/renoise \
--prefix LD_LIBRARY_PATH : "${lib.makeLibraryPath vstLibs}"
'';
});
in
environment.systemPackages = [
renoiseWithVsts
# your other packages
];
</syntaxhighlight>

To figure out what libraries you need, run {{ic|ldd path/to/your/vst.so | grep "not found"}}; ignore the warning about not having executable permissions if you get it. You'll get something like

<pre>
libasound.so.2 => not found
libSM.so.6 => not found
libICE.so.6 => not found
libX11.so.6 => not found
libXext.so.6 => not found
libGL.so.1 => not found
libfreetype.so.6 => not found
libstdc++.so.6 => not found
</pre>

Anything that already shows up in {{ic|ldd $(which renoise) | grep "=>" | cut -d' ' -f1}} will already be loaded by Renoise itself. In this case, we can see we need libSM, libICE, libXext, libGL, and libfreetype. Using [https://github.com/nix-community/nix-index nix-index], we can find the corresponding packages are

<syntaxhighlight lang="nix">
vstLibs = with pkgs; [
xorg.libSM
xorg.libICE
xorg.libXext
freetype
libGL
];
