beamer-vst3

VST3 implementation layer for the Beamer framework.

This crate provides the VST3 SDK integration that bridges beamer-core abstractions to the VST3 plugin format.

VST3 SDK

The VST3 SDK is MIT licensed (as of v3.8), making it available as a standard Rust dependency - no separate SDK downloads or licensing agreements required. Beamer uses Coupler's vst3 crate for the Rust bindings.

Features

VST3 factory: Plugin registration and entry points
Plugin lifecycle: Descriptor ↔ Processor state machine (prepare/unprepare)
Edit controller: Parameter management and host communication
MIDI conversion: Bidirectional mapping between Beamer and VST3 MIDI events
Real-time buffer management: Zero-allocation audio processing
Optional: sysex-heap-fallback cargo feature for heap-backed SysEx overflow (breaks real-time guarantee)

Usage

Most users should use the beamer crate instead, which re-exports everything you need.

Use beamer-vst3 directly only if you're:

Implementing a custom plugin wrapper
Building tooling that needs VST3-specific functionality
