Thanks for replying to my ticket here!
Been quite busy since christmas but I finally got the chance to check out the dbx160 compressor again and see if what you said applies to what I was observing.
At first I was trying it on drum overheads and it still seems to apply more compression with the the sc-filter on than without it. I still don't completely understand why its doing this but I figured this might be due to the compressor reacting more to the cymbals than to the drums at this point. This to me implies that there should be a shift in threshold when the sc-filter is enganged.
The attached audio sample of the compressed overhead track
(dbx160 OH.wav) shows this behaviour. The snare drum initially has about 10db of gain reduction. After two bars the sidechain filter is engaged. The track now clearly has more compression than before. Both on kick and snare drum, at least thats what I hear.
When applying compression only to the kick and snare tracks however
(dbx160 kick snare.wav) I can see more of the behaviour you were describing. The kick gets less compressed, but then again the snare drum also goes from 10 to 12 db of gain reduction when engaging the sc-filter.
So I'm not sure what to make of it. Like I said, my guess would be that there is a threshold change when the sc-filter is engaged, which makes an A/B comparison questionable. Maybe I am missing something.
Can you confirm this?
