Logic: Tempo curve

To create a tempo curve in Logic first draw in tempo changes in the tempo track (using the pencil tool) so that it looks similar to the image below.

Then click and hold the middle node and move it.



The result should look similar to the image below.



To make a tempo curve that slows down, do the same procedure but add and move the nodes to correspond with that type of change. (image below)
