What happens when you use the Grid Mode while editing MIDI?

When Grid Mode is enabled while editing MIDI in Pro Tools, MIDI notes will snap to the nearest time increment defined in the grid settings. This snapping facilitates precise arrangement and timing, allowing users to align notes efficiently according to the established rhythmic structure. By using the grid, musicians can create patterns that are rhythmically cohesive, making it particularly useful for a variety of musical contexts where timing is crucial.

Grid Mode enhances workflow by ensuring that when notes are moved or created, they automatically align with the specified timing subdivisions, such as quarter notes, eighth notes, or any other increments set by the user. This prevents off-beat placements and promotes a tidy, organized MIDI performance. The other options describe scenarios that do not occur in Grid Mode, as it inherently provides a structure for placement instead of allowing free placement or insertion restrictions.
