One of the big questions I always find myself stuck on is how to set attack/release so the layers of compressors in my mixes/masters work best. Eg. DRUMS: 1) Compression at track level (bass drum, snare, etc.) 2) Compression at drum bus level 3) Compression at master level My question: Are there any guiding principles for setting attacks and releases at each level so that this layering will take place best? ie. Is it generally better to start with low attack at the track and go higher attack as you move up to the higher levels? Or is it vice versa (start high attack at track and narrow it down up through the buses)? Regarding release, again, is it generally better to start with low release and go up or other way around? Any personal experiences on the conclusion you find yourself generally working towards more often than not would be handy. Thanks.
