Plugins

Not to be confused with VST and VSTi.

Overview

A MuseScore plugin is a small piece of software that adds extra functionality to the program. A plugin need to be enabled first, and then executed by using the Plugins menu. Some plugins come pre-installed, they are disabled by default. There are also plugins created and shared by other musicians, anyone can download and use them.
