I often get this Question: How can I fit XY sound better into my mix? After EQ-ing the next best thing to do is to create some space for different elements.
I do it with using just 3 Different Reverb Sizes:
Small / Medium / Large
Second thing I do, is: I EQ-ing the Reverb to make it a bit tighter and glued together.
In this video you'll see how I like to think and use reverbs and an actual example how a pad fits way better into a track with reverbs. It actually falls and ties together in almost a magical way.
But honestly, the only thing I did was using different sizes of reverbs and sending different Tracks to them.
