Ok...To me, a basic setup would look a little like this;
*MPC
*Mixer - 8 ins (Atleast 4 Mono inputs) with 3band EQ
*Software Sequencer to record and mix your music in. I.e Cubase,Sonar,Protools etc etc. You only need one
*Midi keyboard controller (2 octave)
*Usb, or a Firewire 4ins 4out minimum Soundcard - Pref 1/4" jack sockets) with or without midi I/O ports -
*Midi interface 2x2 if soundcard don't come with it built it.
*Usb Turntable???
*Active Monitors (Active meaning self powered) $300 range
*Headphones
*cables (1/4 " jacks and possibly RCA phonos)
The exact gear you get is not for me to choose. I suggest you do some research to familiarise yourself with whats out there. Then when youv'e got a few ideas and queries etc check back for some feedback
