When you mix a solo over a rhythm track, do you usually use some automation/envelope to lower the volume of the rhythm tracks and create a little volume pocket for the solo to sit in? I noticed that in a lot of my songs, the perceived volume increases when the solo comes in, because it just sits on top and the backing track is just as loud.
Yeah man always. Also if the rhythms are quad tracked, simply take two away during the solo.
But yeah generally speaking just bring them down 1 or 2 db for the solo section
