After installing Rust, you can compile jverb as follows:
cargo xtask bundle jverb --release
For mac OS M1, you need to build a universal binary for the plugin to work with Ableton
cargo xtask bundle-universal jverb --release
Move to default VST3 folder:
sudo mv target/bundled/jverb.vst3 /Library/Audio/Plug-Ins/VST3
