Creating and Editing Mix Automation

Automation is represented by a series of nodes (dots), connected by lines. Combined, these create an automation curve.

Tip: If no effects have been inserted, you can do this by right-clicking (or Control-clicking) in the Mix lane. Choose Add Plug-in from the shortcut menu and browse to the effect that you’d like to use.

To create automation nodes in the Mix lane
  1. Right-click (or Control-click) in the Mix lane.

  2. Choose the name of the effect in the shortcut menu, and highlight the parameter you want to use in the submenu.

    A colored horizontal line is shown in the Mix lane, and the name of the chosen parameter is shown at the top left (of the Mix lane).

  3. Choose the Pencil tool, and insert nodes by clicking at positions in the Mix lane. As you do this, connecting lines are automatically drawn between nodes, creating your automation curve.

    Tip: Press Command to toggle between the Pencil and Automation tools.
