Setup Help

Wuts up Everybody. I have a quick question. Right now im using FL Studio demo and cool edit pro. But i feel in love wit the mpc 1000. I plan on getting one very soon. I also have 2 turntables and a dj mixer, also a lil midi casio keyboard. I was wondering what else would i need. Ive heard people say a mixer. Could somebody please help me with this situation. Thanks

You've already got more than enough to make beats. Depends what you want to be able to do.
I would say cop the mpc, get everything set up and working smoothly, and learn for a while before you go out and buy more gear.
