do the loops usually havea reversed sound in em... for example

kick kick reverse kick...or does it depend..etc....i hear some cool rhythm.. sounsd liek it goes in reverse for a sec..or it goes A- B A -C ....(MEANING LIKE A SLIGHT HCANGE IN PITCH OR W/E ) i realize its all different..but im shooting for tha tbasic style first..before i distort it how i want it...
