[Digitalsound1]

I apologize if I posted this in the wrong thread. I'm still quite new to ProTools. Just to let everyone know, I'm using a PC and using ProTools LE 8 so maybe the settings could have some differences. The problem I have is keeping a volume settings (is it called volume automation?).

I had a sound at a track that I deleted that had some volume settings that still show in the blank space which is at track 3. When I moved a sound on track 4 volume setting of the sound on track 4 got transferred to track 3. I want to still keep the volume setting for track 3 when I move the sound to it. Does anyone know what I should do?

Also, lets suppose I have a volume setting I want at 3:00 and I am moving a sound around the track. How can I have it where the volume setting does not move with the sound? I don't want to have it permanent, but I just want to have it where I have it both ways where the volume setting moves with the sound or stays in one area. Thank you!
