Do you guys compress the Drum bus
I compress a drum bus, but I always have 2, one compressed one not. I also don't run all my drums through the compressed drum bus, it all depends on the desired sound and the type of music, for example Jazz would have no compression, metal would have lots. A mix I did on the weekend only had the overheads and hats to the compressed buss, they were also in the non-compressed bus.
If so what are your usual settings?
All depends on the player, drum sound, required drum sound etc etc, no usual settings.
and what other effects do you usually put on the Drum bus?
None, the effects are from the channel aux sends, snare, toms, etc, I do feed the effects back into the non-compressed drum bus, or sometimes the compressed drum bus.
I add compression to individual drum tacks before the bus, i.e. the snare and kick tracks. But don't overdo it unless you want a compressed sound.
You may have realised by now that there are no rules, no magic setting, you have to learn by trying things out. However I hope this helped a bit.
