What does the count-in feature in the control bar do?

The count-in feature in the control bar allows the user to set a countdown before playback begins. This is particularly useful for musicians and producers as it provides a predetermined amount of time to prepare before recording starts or before playback initiates. During this countdown, the selected number of measures or beats typically count down, giving performers a chance to get ready and ensure they are in sync with the music.

This feature is critical during recording sessions as it allows a smoother transition into the actual performance and can help align musicians playing together. When enabled, the count-in contributes to a more precise timing and enhances collaboration among multiple players.

The other choices pertain to different functionalities: one provides a visual guide, another results in autosaving, and the last concerns tempo tracking, none of which describe the primary purpose of the count-in feature accurately.
