Hey,
The MC2000 is a virtual analogue synth, it makes whatever sounds you want it to (provided you want to make analogue sounds). Think of the squealing lead sound that Dre used in the early 90's...
Mcrob, you'll probably want to get something like a sound module which has drums, basses, leads, guitars, efx on it so that you have a wide palate of sounds to choose from; the MC2000 will limit you to only analogue sounds. My suggestions would be the Emu Proteus 2000, Triton, or Yamaha Motif.
Take care,
Nick
