Automating Region Effect Parameters

You can automate almost all effect parameters, enabling real-time changes in the way the effect shapes the incoming audio during playback. This is achieved by drawing automation curves in the Region lanes.

Creating and Editing Region 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) a region in the Wave View area. Choose Add Plug-in from the shortcut menu and browse to the effect that you’d like to use.

To create region automation nodes
  1. Right-click (or Control-click) the appropriate region.

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

    A colored horizontal line is shown on the region in the Wave View area, and the name of the chosen parameter is shown at the top left of the region.

  3. Choose the Pencil tool, and insert nodes by clicking at positions on the region. 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.

To select and edit region automation
  1. Choose the Automation tool.

  2. Do one of the following:

    • Choose multiple nodes: Drag across the nodes you want to edit. They are highlighted in a vertical column.

  3. Click anywhere in the highlighted area and drag vertically or horizontally to move your automation data.

  4. Click anywhere outside the highlighted area to deselect your automation data.

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