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 githubhere.

The examples can be built usingcargo-make.

cargo install --force cargo-make

The two current examples areagain andpassthru.

cargo make again cargo make passthru

Provided is a script to package a vst3 plugin as a MacOS bundle, which requires anInfo.plist file andPkgInfo to be included in the vst3 plugin directory.

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 fortodo to find gaps.

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

The COM vtables/API are generated usingcom-rs from Microsoft, it has been altered to allow it to compile/generate code on MacOS and Linux targets. (Update 4/2020) MS has strippedwinapi dependency fromcom-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.
