I've been working with Beatcraft for awhile and I'm getting the hang of it. However I want to work with certain samples im not sure I can get a hold of.

1) Cymbal Rolls, like crash cymbal rolls, are they hard to find? Or even possible to make in this kind of software?

2) Some bands use those really deep metal bass hits that sound like are from a rap song or something? They aren't used very often but sound awesome. If no one knows what I am talking about I can find an example.

Any help would be great.
