check the octane dlr page.they gave away some freebies which were good
also loopmasters-danny byrd,lynx,icicle & friction,fracture,octane dlr,nu tone,london elektricity
for snares maybe try freesound.org
If you look just for drumhits, i recommend our RC Essentials Vol.3 library, plenty of various modern snares and other hits, ready to go and workable to taste, these drums were specially designed for Drum'n'Bass ! I'm sure you will like these hits !
As most of people said freesound.org is great,looperman also..Yes Octane/DLR is a great pack,but i heard so much tunes lately using same snares and beats from this pack,if you don't mind this i think this is one of the best packs you can find!
