I'ma just give you a list of some producer's main weapon's of choice here as I know:
Dr. Dre - he uses a lot of shit but mainly MPC3000 and like workstations like the Korg Triton
Pete Rock - SP-1200 used to be his thing, but recently he stepped up to a MPC2000XL which I think was a mistake cause his beats were better before.
Neptunes - Mad Keyboards ASR-10 used to be but I have no clue what they use now.
Kanye West - MPC2000XL and the ASR-10... His go to machine is the ASR-10 and he used it a lot on his album, but he been gettin away from that and usin the MPC more and more.
Timbaland - ASR-10 to the death... This man has and always will swear by by this machine... now more than ever because he's been gettin that real old school vibe like he used on missy's album... I can't blame him cause it's been workin this long... why **** up a good thing.
DJ Premier - MPC 60 and the E-Mu Mo Phatt... Though you can't judge his equipment cause his production is all about how he uses it cause he is a master of compression and EQ
Madlib - Anything that is labeled inadequate, behind the times, or a beginner piece of equipment has been used by this man... He was using a Dr. Rhythm for a while... Then he was using a Boss SP-303... Then some other cheap shitty sampler with like 10 seconds of sampling time and shitty sounds... Now he's been using the SP-12 which I'm glad to see cause his beats are better than ever...
Madlib is the shit because he proves that it's not the equipment, but the producer that makes the beats what they are... SO big up to Madlib for doing his thing and keepin it old school throughout it all while still maintaining some of the most innovative beats in the underground.
