id personally use autosnap.

once detected they can be turned in to a midi sample. with this sample you can use it to trigger any drum via softsynth ala session drummer, dimension pro, exc.
as shown in this video.
its one of the reasons autosnap was put in to sonar.
then again I don't see your specs so I may just be wasting both yours and my time if you don't have sonar and instead music creator, sonar homestudio, exc.
