When Advanced Editing options is selected in the Advanced preferences pane, you can also sort tracks by choosing one of the options in the Track > Sort Tracks By menu.
You can reorder tracks in the Tracks area. Changing the order of tracks doesn’t affect the sound of a project, but lets you organize tracks visually to keep instruments in a particular order, or keep related tracks together. For example, you can keep all drum tracks together, or keep all tracks that double the same melody together.
