What equipment would I need to buy to DJ with my MacBook Pro?

@tyrantxseries Thanks, homie. I will check out that site!

OK, so that tells me where I could buy things from, but what do I buy?

that would depend on what kind of DJ you wanted to be.
the link above also describes what the equipment does

I DJ occasionally with a toslink cable which takes your headphone connector and changes it to optical which provides nice sound. If your less of a pro just go to radioshach and pick up a splitter that changes the headphone port to the regular analog white and red connections. You also need to get a extender for the headphone port.

Check out virtualdj. For basic mixing and effects it is a good start, plus you don’t really need extra equipment.

Sounds like he was using a software DJ system-there are many. The most prolific ones are Serato Scratch and Traktor DJ. They use an external sound box that interfaces the turntables with the computer. The box has two “sets” of sound outputs that allow the DJ to hear a separate feed (the Cue mix) from what the audience hears (the “Program” mix).

The box also listens for time code signals (inaudible to the audience) which are played from special vinyl records (the records themselves don’t have music on them), which allow the DJ to control elements of the song that’s on the computer (tempo, cue point, pitch, etc.) The Serato system is extremely sophisticated, as it allows for scratch emulation of the digital audio file for each “deck” (remember that a DJ mixes two signals together).

A system like (without the laptop) usually runs in the $500—$1000 range, and you still need a mixer (an analog mixer in the case of Serato) if you want to have “old school” style control over the system.

The Traktor system doesn’t require a turntable, but has that same option for controller. In the Traktor system, you can control the cueing, mixing, and other features with a MIDI controller (a tactile surface that emulates the look and feel of an analog mixer).

One other place to look that’s decent is M-Audio, they have a similar product called Torq which is somewhat on par with the other two. Best advice-go to a Guitar Center or other Pro Audio place and try out multiple systems to get a hands-on test drive.

@sndfreQ You have the right idea, my friend. That was an extremely comprehensive answer; I have leads to go on now! :)

Right on man…I’d say unless you have a lot of vinyl already, try DJing via computer and MIDI controller first to make sure you really want to pursue it full time vs. a hobby, as getting into the turntable aspect can run you upwards of $1K for the tables and a mixer, and a serato box/software, etc.

Also, you may want to check out beatport.com for some remix ideas…a lot of genres, and it’s basically similar to iTunes music store, but more for DJs…also ccmixter.org for open (Creative Commons) content. If you decide you’re into remixing, try foem.info and indabamusic.com (I prefer the latter).

I also have a MBP and just ordered M-Audio Torq MixLab to hopefully start with something. From reviews I read, its a good intro device into laptop DJ-ing, and the price is alright too. The package will come next month. I’ll tell you how it goes, if I remember to…
Also got myself some Behringer headphones to replace my broken Sony’s. Behringer’s are cheaper but are also good entry cans.
btw, I used to dabble with analog mixers and synth, and some tracks with Garageband.
Trying to get more into dj music making only now.
