im not sure what software or vsts your using but if your rolling kick drums you wanna set the sample poly to 1 so it wont play more then 1 kick at a time.

Because if your flying a string of kicks off and they overlap it gets nasty.

and youve also got the right idea when you mention killing bass, although depending on the effect you want from your roll a lot of tracks have a high pass filter over the kick in sections, so you can bring the cut off up and trim away the lower end. works really well when going in to a break also, slowly filtering away the low end from the kick fading it into the background till it becomes a light tap.

hope this helps
