Drum sample problem

[cambo]

Hi all, I'm really new to this game and have just purchased cubase se. I just downloaded a platinum drum kit from wizoo for use in halion se. Problem is, a closed hi hat hit doesn't shut off the open hi hat and I can't find anywhere to fix it.

I know halion se is a lite version without any fancy editing abilities, but surely it will allow me to load a basic instrument and have it work like a drum kit.

Any help on this, appreciated.
