Cubase supports bézier automation curves that allow you to create smooth transitions between automation events. This way, you can edit linear ramp curves with more precision, flexibility, and intuition.
Prerequisite
The Object Selection tool is active.
Procedure
Result
A smooth transition curve is created, reflecting your edits.
If you are not satisfied with the result and want to start over again from the original linear curve segment, double-click the handle.
After Completing This Task
For even more precise editing, add new automation events to your bézier curve segment.
This creates new segments that you can smoothen.
