Do you remember Meowsynth? So do I. Unfortunately, it seems that Meowsynth is only 32-bit and hence isn't compatible with many 64-bit DAWs (in particular, it's not compatible with Ableton, which doesn't support 32-bit VSTs any more). Additionally, there isn't a Mac or Linux version.
To build the plugin as a vst3 bundle, run the following command:
cargo xtask bundle nyasynth --release
This will create a nyasynth.vst3 bundle in /target/bundled/. Install this into any vst of your choice.
You can also create a standalone binary by running the following command:
cargo build --release --bin standalone
This will create a standalone binary in /target/release/. You can see the arguments it uses with standalone -h. See nih-plug for more information.
