Hey, if you want to achieve real sounding drums and drum sequences, your best bet would be the MPC 500 or better. It does so much, and simplifies building complex drum lines. Dnb music is what it is today because of how the sampler works. All early stuff was done on the MPC. Repeating snares and buildups are all technics done on such equipment. What this and see if this suits your fancy. An 808 will never sound like what you want. It will always have that electro sound to it. http://www.youtube.com/watch?v=EE3UN7CMByQ
dont get me wrong, but whats the point of spending all that money on an 808 when you can get probably millions of 808 samples online and manipulate them 100x more than you can on the original thing..... also, what happens when you get bored of 808 drums???
dont get me wrong though... its a sexy thing to have!!
