Stock Drum Kits

Does anyone know if I can copy samples from one stock drum kit to another?
(Appetite, Battery, Dawn, Fringe, etc)

Or where I can find these samples for an empty kit?

You can!

Well, that’s grabbing from the original kits from several versions ago. If you actually create a stock kit, you can see which sample has been used for each sound. Just make an empty kit with the sounds you like most.
