I've been experimenting and learning while doing, with compression on my tracks, in particular this side-chain business for kick and bass, which is a great trick which has opened my eyes and ears to all the professional music around me. Many thanks to all for your wonderful forum-advice so far
While experimenting, I noticed a dial on NS2 Compressor called HOLD, which I didn't see on other compressors. Now if my instinct serves me, this would be like the D or the S in ADSR waveforms, so the compressor has Attack time, Hold time and then Release time. A quick google seems to confirm this idea.
What I would like to know is - how do people use this in their projects? Do they use it? How do you all decide what time settings to use for the attack, hold and release dials, without knowing the number of milliseconds that the kick lasts, for example?
At the moment I'm sort of winging it by ear, for my sidechain compression settings; a pretty fast attack to duck the synths&bass at the very start of the kick, and then a little bit of hold to allow the kick sound through, then a fairly quick release to bring the synths back in. If I get lucky I can time the synths to come back on a 1/4 or 1/8 beat which seems to sound pretty nice. But my sense is that there could be a more scientific / mathematical /professional route for these millisecond choices.
I realise it's a BIG topic, so am just interested for any obvious pointers and tips, or 'usual practice' ideas, to get me pointing in the right direction - thank you!
