You solo the kick drum, add an EQ plugin, and tweak it until the kick sounds great. You move on to the snare, solo it, and do the same thing. Then you solo the vocals and compress them in isolation. And you slowly move through your mix, using the solo button to shape each track individually.
It’s tempting to work this way. After all, it’s easier to focus on one track at a time. Since you’re not being distracted by other sounds, you can hear subtle changes more clearly. And this helps you make better choices, right?
“Your signal processing chain (that is, the order of your plugins on each track) will most likely reflect the order in which you address different aspects of your mix. In this process you may have experimented with the order of two specific tools, the compressor and EQ. Does one necessarily affect the other?”
