I think I know how to view and change track automation, not sure about region but assume its the same. There is typically just a straight line in the automation at the level of the volume when I get the tracks and I don't see any strange up and down volumes on the automation track. The tracks I am using are from Hitrax and are backing tracks for vocals so the midi is, I believe, one region. I have noticed that the tracks have a small white vertical lines where this problem is occurring but I don't know how to change them.
