I have several tracks open and some of them have the highest value on the fader as 0 db and some go up to +10 db. How can I change this? I thought I created them all the say way and they are all audio tracks, but I can't seem to figure out how to switch them. Now when I try to create new tracks they all start with 0 db, so I don't know I created with the extra headroom before. I'm sure this is an easy answer but I can't figure it out. Thanks!
