There is now a nightly build of the SignalFunctionSet plugin on GitHub. It rebuilds on every commit, so you can try fixes and new modules before they reach the VCV Rack Library.
You can grab it from the nightly release page. Builds are there for macOS (Apple Silicon and Intel), Windows, and Linux, all 64-bit.
What you get
The nightly is the same plugin as the Library version, plus whatever I have committed since the last release. That includes work-in-progress modules that are hidden in the stable build. Right now that means Wave and Ratio, which are not finished but are far enough along to patch with.
If you want to follow along as modules take shape, or you hit a bug that is already fixed in the code but not yet released, this is the build to use.
Install it alongside the release
The nightly is a separate plugin, not a replacement. It has its own slug (SignalFunctionSet-nightly) and shows up in Rack as Signal Function Set (Nightly), so it installs next to the Library version without a conflict. You can run both at once.
To install: download the .vcvplugin for your platform, then in Rack open the Help menu and choose Open user folder. Drop the file into the plugins subfolder and restart Rack. It unpacks on launch.
Two things to know
Because the nightly uses its own slug, patches you build with it are not interchangeable with the Library version. A patch saved with nightly modules will not find those modules in the stable plugin, and the reverse is also true. If you plan to share a patch, build it with the Library version.
The nightly builds are unsigned, so on macOS you may see a warning the first time you load one. That is expected for a build that does not go through the Library.
Join the Discord
The nightly posts to the SignalFunctionSet Discord every time it builds, so joining is the fastest way to know a fresh build is ready. It is also the best place to send feedback. If you are trying the work-in-progress modules, telling me what works and what does not is what turns them into finished ones, and bug reports there tend to get fixed and land in the next nightly quickly. Come say hello.
Stable releases still come through the VCV Rack Library as always. The nightly is there for when you want to see what is next.
