do you have flstudio 4 or fruity 3..cause theay changed the name of the product for some reason but..if you have flstudio 4 pro edition theay have this thing called a slicer...now with that you can upload samples,like say you go buy you a classical music cd..
you take what sounds you like from that cd..make minute samples of theam...and upload theam thru the slicer..if
you slice it at 1/8 it'll brake that sound down into little pieces of that sample probably up to 146 times...you just make a patteren out of that and follow it with nice hip hop kicks and snares and high hatz...the key to a good rap beat is rhytem..flow of the beat..
set your tempo at about 89 to 95 and fuck with the drumz...try this and holla back
