im downloadin the sample and ima try and help u. but i do know that if u cant put drums over a sample you need practice and alot of it. drums is just a very little part of doin the beat. findin the sample, choppin the sample, arrangin, puttin down your bassline, and mixin is all part of your beat. so if u cant simply do drums then u gon have a very hard problem to figure out when u get to everything else.
aight first of all let me say good sample and nice chops. but this is very very easy to put drums on. im gon put drums over it and upload it to my soundclick page for you to see how simple it is. then just try and do somethin like that. and i will take the beat down off my page.
