I have Logic Express 9. I work for a church doing a radio program each week. When I import pre-recorded audio, often the volume levels don't match up. How can I change the level of one region (I think that's what they are called - in other programs they are called clips) before I mix the whole project down? I know there is a "normalize" function on mixdown ("bounce"), but that's not what I want. I want to change the volume of individual clips before mixdown.
