Bend automation curves in Logic Pro for iPad
By default, the automation curve is a series of straight lines that connect one automation point to the next one. However, you can bend each line segment individually to create curved lines.
Change the shape of automation curves
Tap the Automation View button in the Tracks area menu bar (for track automation) or the Editors area menu bar (for region automation), or press A on your external keyboard.
Tap the Curve button in the menu bar, then drag any line between two automation points in a specific direction:
Dragging up or down bends the line to an exponential curve. The dragging direction determines whether the “knee” is at the beginning of the line (the help tag displays a negative value during the drag movement) or toward the end of the line (the help tag displays a positive value).
Dragging left or right bends the line into an S-shaped curve. The direction determines whether the orientation of the S shape is upright (the help tag displays a positive value and the letter S) or the S shape appears sideways (the help tag displays a negative value and the letter S).
Note: You can first select a section of the automation curve (even noncontiguous), and then dragging one of the selected lines will apply the same shape to all selected lines.
Tip: When you tap the Curve button and then the Stepped Automation button (to select both buttons), you can tap a selected automation curve to have its shape alternate between curved and stepped automation. See Stepped automation curve.
