don't produce drum & bass, but im finding the sample pack that came with last months computer music (the dubstep one issue #132) really handy for more than one genre.
some grimey samples on there
nothing beats the free samples with cm124 though..... the dub edition..... fuck yeah!!!!
might have to back order that shit, do you what the sample packs the drums are all from?, they usually take a selection out of certain kits.
