VST 3 - Audio Unit v3 Wrapper

Helper Class wrapping a VST 3 Plug-in to a Audio Unit v3 Plug-in

Introduction

The VST 3 SDK comes with a helper class which wraps one VST 3 Audio Processor and Edit Controller to a AUv3 Plug-in.

The wrapped AudioUnit does support MPE when the VST3 Plug-in has Note Expression support. You need to implement Steinberg::Vst::INoteExpressionPhysicalUIMapping to map your Note Expression to the limited three expressions defined by MPE.

How does it work?

• Structure:
  • App (container app which initializes the AU through small Playback Engine)
  • Extension (extension which is loaded by hosts, also initializes the AU)
• How-To use the VST3->AUv3 Wrapper with the sample code:
  • make sure you have correct code signing set up
  • build & run targets
• How-To use the VST3->AUv3 Wrapper with your own VST Plugin:
  • duplicate either the folder again_auv3 or note_expression_synth_auv3 in public.sdk/samples/vst, rename it as you like and edit the CMakelist.txt to add your sources, resources and modify target names etc.
  • take special attention to the stuff in audiounitconfig.h and change the definitions in there.
  • also change the other files in that folder to your needs. -Code signing is required, but you can build and test with a developer only identity.
  • build & run targets
