The Alesis MasterLink has a feature called Normalizer. It basically scans your entire track for the highest volume. It than applies a multiplier so that the peak volume equal to full scale. In other words, after normalization, all your tracks will have the same peak volume. Nomalizer is not ALC which may compresses dynamic range. It works really well but you have to run normalizer a track at a time. Also, you don't want to run it on quiet passage of classical music or you will make them sounded as loud as the loudest passage.
