Hi, I'm about to purchase a Mac Book Pro, when my 12" PowerBook G4 finally quits and hopefully when the chips are upgraded. On my PowerMac, I have dabbled my hand with DJ'ing using Traktor, and as much as I like the app and know how to DJ, I ind it tremendously difficult without the help of a mixer, headphones and stereo output. What I intend for when I get my MBP is to have my dance music collection stored on it, so I can DJ, but also have some kind of mixer input so mixing is easier, and also so there is a headphone jack so that I can listen to the song which is not playing through the speakers to beat match. What do I need other than a MBP, Traktor and headphones. I know I need some kind of mixer, but what kind? It is essential for me to have all the connections so that I can output my mix, but also listen to the song which I plan to bring in next. What do I need to do this? I feel that at the moment turntables are not essential to mix on the Mac, just the mixer, but I would like other peoples opinions on this, as I plan to mix mainly garage and dance, and not so much hip-hop and scratching. Thanks for any help!
