Composition will likely mean different things to different Pro Tools users. It may mean writing notes to be played by musicians playing acoustic or electro-acoustic instruments. Or maybe you will be constructing patterns and textures for electronic music, or beats for rap and hip-hop music. It may mean arranging or adapting someone else’s music into your own creation. Or perhaps you are forming ideas about sound effects to accompany a film, a live theatre production, or even a video game. While it’s fair to think of plug-ins as tools used primarily during editing, mixing, and mastering, there are a few useful ways that some plug-ins can help in the composition or song-writing process.
