i hope my hip hop cats out here realize that most of the kicks, snares. and etc are also sounds you did not make yourself. Unless you got reason 5, most of us have to tweak already made samples... I don't see how people can hate loops or sampling so so much when we live in a world thats been "done over" in every aspect, 1000 times.
Modify, Shape, and Chop as much as needed or leave it the way it is, as long as your finished product is something that you feel is creative to shine.
