Tells you they are out of keys AFTER you complete the required actions . Bunch of X $#%<| sep |> There is a risk that if you have used your main kick for the sidechains then later you lower the volume of the kick then you would need to reset the compressors settings . You should never change the volume of your ghost kick so you shouldn ' t have to reset the compressors in the event that you lower the volume of your main kick . and since modern EDM is just like side chain everything it then becomes a cleaner workflow . I ' m not really a fan of the ghost kick with everything however . I feel that proper gain staging negates the need to do this and I prefer bespoke settings for my sidechains . I will use a ghost kick if my actual kick is part of a percussion loop or something and it is not providing a clean signal for the compressor . One could use the compressors input filter but I am even less of a fan of that . I have a bit of a hard on for using clip fades and volume automation as an alternative to sidechain compression .
