80 Chapter 9 Tutorial 7: Mixing and Adding Effects
To lock automation control points to regions:
m Choose Control > “Lock Automation Curves to Regions.”
All control points are locked to the region corresponding to the automation curve.
The following conditions apply to locking control points to regions:
 Shortening or lengthening a region has no effect on its control points.
 Deleting a region deletes its control points as well.
 If you overlap a region containing control points with another region, both the
control points as well as the region are shortened.
 If you drag a region containing no control points over part of a track containing
control points, the control points are locked to the new region.
 Looping a region does not loop its control points–instead, copy the region.
To delete an automation curve for an effect parameter:
1 From the pop-up menu on the left side of the track’s automation row, choose Add
Automation.
2 When the menu appears, deselect the checkbox for the parameter you want to delete.
You can select multiple parameters.
3 When you are done, click OK.
Note: When you delete an automation curve, all the control points on that curve are
also deleted. This cannot be undone.
