I should've added that the compression works fine as you are simply trying to "stop" those attack transients from being audible and making you hear each specific "hit" of the cymbal. The sample chopping is a work around so you don't have to give up your compressor for the cymbals if you have other things you need to use it for.

But maybe you have a computer with 300 different software compressors in which case I'd recommend the aluminum foil face slapping. :-)

good luck!
