Help w/reason and sound fonts

Hey, I'm trying to use the free ns7kit in Reason, and I'm having a very specific problem - I can't seem to figure out how to cut off the sample when the key is released. Instead of a key just triggering a sample, how do I make it so that when the key is released, the sample stops playing, like for the open high hat or cymbals?

Set the Amp Release value all the way down.

Okay, but I don't necessarily want it to do that ALL the time.

Ah. Forgive me... this is my first time ever attempting to use this stuff.
