Beamer

VST3 Framework for Rust.

Beamer is a framework for building VST3 audio plugins with WebView-based GUIs. It provides safe Rust abstractions over the VST3 SDK.

Architecture

Your Plugin (implements Plugin trait)
       ↓
Vst3Processor<P> (generic VST3 wrapper)
       ↓
VST3 COM interfaces

Quick Start

use beamer::prelude::*;
use beamer::vst3_impl::{Vst3Processor, vst3};

// Define your plugin
struct MyGain { params: MyParams }

impl AudioProcessor for MyGain {
    fn setup(&mut self, _: f64, _: usize) {}
    fn process(&mut self, buffer: &mut Buffer, _aux: &mut AuxiliaryBuffers, _ctx: &ProcessContext) {
        // Your DSP here
    }
}

impl Plugin for MyGain {
    type Params = MyParams;
    fn params(&self) -> &Self::Params { &self.params }
    fn create() -> Self { Self { params: MyParams::new() } }
}

// Export
static CONFIG: PluginConfig = PluginConfig::new("MyGain", MY_UID);
export_vst3!(CONFIG, Vst3Processor<MyGain>);
