vst3-sys

A port of the VST3 API in pure Rust.

We do not distribute the SDK nor try and wrap it in clean abstractions, just port compatible bindings to the COM API. The full SDK can be found at sdk.steinberg.net or cloned from github here.

Building Examples

The examples can be built using cargo-make.

cargo install --force cargo-make

The two current examples are again and passthru.

cargo make again 
cargo make passthru 

Provided is a script to package a vst3 plugin as a MacOS bundle, which requires an Info.plist file and PkgInfo to be included in the vst3 plugin directory.

Completeness and Contributions

Currently this crate is missing definitions of some of the constants found in the SDK, and help covering them would be greatly appreciated. If you find something missing from the SDK please submit a PR to add it. You can also grep for todo to find gaps.

This crate intentionally omits anything not a part of the COM-compatible API.

Credits

The COM vtables/API are generated using com-rs from Microsoft, it has been altered to allow it to compile/generate code on MacOS and Linux targets. (Update 4/2020) MS has stripped winapi dependency from com-rs and it's closer to being suitable for cross platform development. Currently outstanding are some of the implementation details of the runtime and the calling convention of the generated vtables.
