Here are some of the users that use the MS2000 only one is rap but if you can get some sound sample from the internet check it out before u buy
I own one and it has great bass it takes place of the korg ms20korg prophecy and probably more but those are the one I know of.
BT, Depeche Mode, Apollo 440, the Crystal Method, Placebo, the Faint, Royksopp, and Snoop Dogg.
Analog Bass is very straight forward if you know how to dial it in. Any synth with a square and a saw will shake stuff off your tables.
The basic idea is this :
VCO: Sqr and saw mix 10/7, just raw- no noise or sub osc
VCF: Cutoff low (2/10) Res all the way down, little bit (2/10) of ENV mod, keyboard track at 50%. If it sounds super low increase the cutoff. Everything else 0 (LFO mod, etc)
VCA: A=1.5 D=7 S=10 R=2.5
That should put you in the ballpark for any synth to get big sustaining bass.
If you want to sound just like lil' John, Novation A station. He has two of them and were used alot on the album
If you wanna get that west coast sound Korg is fine,but if you like dj quik,battlecat type basses,a studio electronics Se1 or an atc of course they have the newer se1x and atcx I would get an se1 for say about 3-400 and you can upgrade to an x for about 3oo wich isnt necessary just an option
