Reorder tracks in the Tracks area
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.
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.
Hold down an empty part of the track header, then drag the track up or down.
Choose Track > Sort Tracks By, then choose an item from the submenu:
Used or Unused
