That Presonus 8-Channel compressor is great if you need lots of comressors and gates. I use it every time I want to record a lot of drums. I use the compressors when I track, and the gates when I mix. I use the gates even on vocals as well (if I want that; a lot of times I don't), but the compressors I'd only use for drums unless I'm out of compressors for other intruments.
