Pro Tools has the ability to automate what it calls “Volume Trim”. This is something I used quite frequently in PT and I am really missing in Cubase. Volume Trim, rather than automating the volume, it automates adjusts made to the volume. So, it allows you to change the volume at any point in your mix using the fader and then still be able to apply automation that moves the volume up or down. I would love to see this feature in Cubase.You could also automate the volume and then decide you want to experiment with additional changes to the volume and temporarily automate the volume trim. It just makes volume type automation much more flexible.
Part of the discussion from my Cubase Disadvantages post is about this topic.
