hi, i m new user so i’m learnin thru trial n error, to answer your question
first pick a drum sounds via vst or a drup loop, now u may like some thing in those sounds/ loop, so u can cut / stretch , compress, edit those loops to ur taste and groove that ur aiming for.
to edit open the sample editor it comes up when u click the event. in the editor u have warp, hit points, that can help u slice, stretch , compress, define the grid to help u achieve your task.
check you tube for editing drums n try those things, its little challenging but not impossible, i find d manual not so lucid, try getting on forums of homerecording, gearslutz theres lot of good help there.
honestly people r not helpful here, its foolish for them so queries get dumped.
