Which of the following is NOT a function of regions in Pro Tools?

Regions in Pro Tools serve multiple purposes that enhance the functionality and workflow within audio production. One of their primary functions is playback control of audio clips, allowing users to select and manipulate sound files during the mixing and editing process. Additionally, they play a crucial role in the arrangement and editing of audio and MIDI, enabling users to organize and modify tracks effectively. Furthermore, regions also facilitate the automation of effect parameters, allowing for dynamic changes in audio processing over time.

Backing up the entire session is not a function associated with regions. While managing regions is essential for organizing elements within a session, backing up the session typically involves saving the entire project file along with its settings, effects, and recorded audio. This process goes beyond the capabilities of individual regions, as it encapsulates all components and files associated with the Pro Tools session, ensuring that the entire project can be restored if necessary.
