NIH-plug
This is a work in progress JUCE-lite-lite written in Rust to do some experiments
with. The idea is to have a statefull but simple plugin API that gets rid of as
much unnecessary ceremony wherever possible, while also keeping the amount of
magic to minimum. Since this is not quite meant for general use just yet, the
plugin API is limited to the functionality I needed and I'll expose more
functionality as I need it. See the documentation comment in the Plugin trait
for an incomplete list of missing functionality.
Current status
It actually works! There's still lots of small things to implement, but the core functionality and including basic GUI support are there. Currently the event loop has not yet been implemented for macOS, and the Windows version should work great but it has only been tested under Wine with yabridge.
Building
NIH-plug doesn't use any unstable features, and works with the latest stable Rust compiler.
After installing Rust you can compile any of the plugins
in the plugins directory in the following way, replacing gain with the name
of the plugin:
cargo xtask bundle gain --release --bundle-vst3
Example plugins
The best way to get an idea for what the API looks like is to look at the examples.
- gain is a simple smoothed gain plugin that shows off a couple other parts of the API, like support for storing arbitrary serializable state.
- gain-gui is the same plugin as gain, but with a GUI to control the parameter and a digital peak meter.
- sine is a simple test tone generator plugin with frequency smoothing that can also make use of MIDI input instead of generating a static signal based on the plugin's parameters.
Licensing
Right now everything is licensed under the GPLv3+ license, partly because the VST3 bindings used are also GPL licensed. I may split off the VST3 wrapper into its own crate and relicense the core library under a more permissive license later.
