Now I am playing with the parametric EQ. What I have not figured out is how to link EQ channels together to adjust them in relative mode. For example, let's say that I have done EQ to my left tweeter and then to my right tweeter to get them to be equal in level across their playable range. Now I want to make a tonality adjustment without losing my relative levels between the left and right side. How do I make this adjustment in Tun?
