hey I actually saw a 2nd grader DJ in a hiphop show before, DJ Kid or something?

Naw software doesnt totally take the fun out of it, like Oneel said in another post, allows for more creativity. 

no... or yes... you need 2 sound cards OR... you need 1 sound card that can process audio as seperate outs. Soundblasters won't do that. You would probably have to spend about $150-200 to get something that does. You need an m-audio interface. I just bought a Fasttrack Pro and I cannot overstate the value it has brought me in just a few days of use.

Well... my SB live couldn't do that.

painful phrase but I believe we all go through that...  right now I got some extra money and I was like, "Yes! The money for my new headphones!" and then I remembered that I need tires for the winter...  I guess sometimes we just have to wait... 

Chris, no reason to be ashamed or embarrased. Good news! Hardware is a waste of money!  and ableton live 6 demo does more and is free - http://www.ableton.com/downloads , you can do your set plus add vocals plus another background track for 4 tracks total, can't save or export, but just send to minidisk or another computer.

please forgive me for digressing, but i will take this opportunity to speak my humble opinion about modern dj'ing.  it is basically now silly to nudge a slider gently for 4 minutes up and down for each song for 4 hours.  with m-audio's torq
http://createdigitalmusic.com/index.php?s=torq and/or ableton live, there is really no need even for decks or cddjs, except to go "wicky wicky" and bust a funky chicken elbow / "thumbs-up" combo to the crowd. 

<insert traditional rebuttal here>

dj's are now producers with ableton live and these kinds of things, and if they are not producing, chances are the phone is not ringing.  harsh to say, but i do believe she's a true.  so much more can  be done now, you don't need cddj's, the tactile feel really only translates to cueing tracks, which you can do with your eyes now anyway. this is also to say nothing of the vj'ing and dj'ing combination possibilities with free tools like www.vvvv.org, you can scratch with a nintendo ds for example, take one look at the remix/dj racks for manipulating audio in real time in live 6 and i think you will agree that 400 for a low end cdj is laughable, or 99 for that matter. plus you can warp quicktime with live, not to mention run a realtime visualization plugin for the club's projector and tweak that as well, with metadata info, Scripture, etc., or run a video podcast.

additionally, there are about 1.2 quajillion free dj tools at http://www.linux-sound.org/ - burn a 10 cent cd-r and boot from a cd, there you go, countless opportunities with mp3's etc.

there is a tiny learning curve to some of the software, but if i can do it, trust me, you can do it, if you look at some of the videos on youtube to see what people are doing with audio and video, i think you will be excited to forego the "old school" <sniff, sniff> of watching that beautiful platter glimmer in twighlight, for the cheery future of laptop-encrusted technodom. maybe after a little while, get a sweet little hardware controller like x-session, which basically seals the deal with software.

hope that helps bro, live is more fun anyway, and you won't get that crick in your neck from headphones
