native instruments maschine is stocked with killer drum sounds for all kinds of music and has really good hip hop and digital sounds. I also got battery 3 and just use alot of the free stuff ive had over the years and just stack and pitch the sounds in battery which is pretty easy to do. Note that this is very very time consuming, hell for me to be happy with 61 of my own drum sounds it would be close to 2 days of work which includes picky sounds,exchanging one sound for a better sound and stacking it,pitching,blending the sounds,filters if needed,eqing,and just making sure its what i want. Some times just buying drums is easier but alot of the time you will only like not even half of what you get or its just recycled garbage thats been out for years like dr dre,timbaland,just blaze's drum sounds. But creating your own sounds is what will make you stand out cause it will be only you that will have these sounds and having your own sound is what makes producers great thats if there good sounds. timbaland and polo da don are big on making there own sounds in fact polo said he dedicates his self to a few days of making new sounds to get more of a creative flow going and inspiration which is the truth right there.
