Which Edit mode should be used for clip start "snap" to grid boundaries?

The most suitable Edit mode for achieving clip start "snap" to grid boundaries is Absolute Grid mode. This mode ensures that any clips or selections in the timeline align precisely with the set grid lines, which can be predetermined according to the session's tempo and meter. When using Absolute Grid, dragging a clip will snap its start point directly to the nearest grid point, making it particularly useful for achieving precise placements and ensuring rhythmic accuracy in your arrangement.

In contrast to Absolute Grid, other modes like Slip and Shuffle do not offer this specific snapping feature to the grid. Slip mode allows for free movement of clips without any restrictions, meaning you can drag clips anywhere in the timeline regardless of the grid. Shuffle mode also presents limitations, as it is designed to automatically close gaps between clips rather than snapping to a grid; thus, it might not align the start of clips as desired. Although Grid mode does snap to grid lines, it does so in a more flexible manner than Absolute Grid, where selections may not necessarily start exactly on the grid if they are moved. Therefore, Absolute Grid is the ideal choice when precise alignment with the grid is required.
