The VST 3 SDK (Virtual Studio Technology Software Development Kit) is a collection of software development tools included in one package. This allows plug-in developers to create plug-ins in VST 3 format and host developers to load VST 3 plug-ins into a DAW or audio editor.
The VST 3 SDK package contains:
This is a C++ interface defining how a VST 3 plug-in communicates with a host and vice versa. The heart of VST 3.
Check the folder "pluginterfaces/vst" of the SDK!
Some helper classes are provided, implementing some VST 3 interfaces for hosting and for creating VST 3 plug-ins. Simply derived your plug-in C++ classes from these helper classes.
Check the folder "public.sdk" of the SDK!
The SDK includes some Plug-ins implementation examples.
The SDK provides a test application called VST3PluginTestHost for Apple Mac OS X (x86_64/M1) and Microsoft Windows (64bits).
This open source application (Win/macOS) allows you to generate easily a new VST 3 plug-in project by just entering in a GUI some parameters.
The validator is a small command line host application (source code included) which can be used to check your plug-in for VST 3 conformity.
Simple cross-platform (only tested on Linux) host application allowing you to register a VST 3 plug-in with Jack Server.
Simple cross-platform (Win/macOS/Linux) host application allowing you to open the editor of a VST 3 plug-in.
Simple cross-platform (Win/macOS/Linux) host application, built with VSTGUI, which scans the VST 3 Folder, collects information from the factory about each VST 3 plug-in and display it in its UI.
This is a user interface toolkit mainly for audio plug-ins (VST, AudioUnit, etc). Based on the XML definition of the plug-in UI, VSTGUI includes an embedded editor (UIDescription Editor) which allows the developer to create a plug-in UI just by drag & drop of the UI element.
These wrappers allow you to create versions of your VST 3 plug-in in other plug-in formats with minimum effort.
