A while ago I found this outline for compressor settings at www.orange-fields.com/widepages/drumscomp
It was useful to me so I thought I'd share. If they're your settings, let me know and I can attribute them to you or remove them if you wish but thanks for the help.
DRUMS - COMPRESSION
(A variety of different settings !)
KICK -
1) To "flatten" = 8:1 or more, short attack 2ms or less.
2) For more "attack" = slow the attack time to let the initial "poke" through.
3) 6:1, Threshold = -3 to -5dB.
4) Between 4:1 & 8:1, attack about 10ms, rel. about 200ms.
5) 10dB gain reduction (maximum !)
SNARE -
1) 3:1, Threshold = -10dB to add "crack".
2) Between 4:1 & 6:1, attack = 5 to 10ms, rel. about 150ms.
3) 10dB gain reduction (maximum !)
OVERHEADS -
1) 2:1 to lengthen signal decays.
TOMS -
1) Between 4:1 & 6:1, attack = 5 to 10ms, rel. about 150ms.
ANY DRUM -
1) 4:1, 5dB gain red. as starting point. Use AUTO (or attack 40 to 50ms, rel. 300 to 500ms.)
