final class MyProcessor implements Vst3WorkerProcessor {
  @override
  void initialize(double sampleRate, int maxBlockSize) {}

  @override
  void setParameter(int paramId, double value) {}

  @override
  void processStereo(Float32List inputL, Float32List inputR,
      Float32List outputL, Float32List outputR) {
    outputL.setAll(0, inputL);
    outputR.setAll(0, inputR);
  }

  @override
  void reset() {}

  @override
  void dispose() {}
}

void main(List<String> args) {
