What is the VST 3 SDK?

Getting Started

  • VST 3 Links — Important links you will need for working with VST 3
  • How to setup up my system for VST 3 — In order to build VST 3 plug-ins, you need the source code of the VST 3 (API: interface definition), an IDE/compiler, cmake and a VST 3 host application.
  • Preparation on Windows — Generated VST 3 Microsoft Visual Studio Projects using the cmake files included in the SDK will create by default symbolic links for each built plug-in in the official VST 3 folder, in order to allow this on Windows you have to adapt the Group Policy of Windows.
