– the Attack and Release Settings can Do a Lot to Push and Pull Sounds in the Front-Back Dimension

– Faster Attack Settings Subdue Your Transients and Make Sounds Feel Further Away

– Slower Attack Settings Let the Initial Impact Through and can Make a Sound Feels Like it is Close and Coming Right a You 

– Faster Release Settings Bring Up the Sustain and Gritty Resonance of a Track, Making it Feel Very Upfront and Immediate
