Editing Virtual Studio Technology (section)

== Programming languages ==
Steinberg's VST SDK is a set of [[C++]] classes based around an underlying C API. The SDK can be downloaded from their website.

In addition, Steinberg has developed the VST GUI, which is another set of C++ classes, which can be used to build a graphical interface. There are classes for buttons, sliders and displays, etc. Note that these are low-level C++ classes and the look and feel still have to be created by the plugin manufacturer. VST GUI is part of the VST SDK and is also available as a SourceForge project.<ref>{{cite web | url=http://sourceforge.net/projects/vstgui | title=Vstgui }}</ref>

There are also several ports to other programming languages available from third parties.

Many commercial and open-source VSTs are written using the [[Juce]] C++ framework instead of direct calls to the VST SDK because this allows multi-format (VST, Audio Units and Real Time AudioSuite) binaries to be built from a single codebase.
