9/10 almost exactly a year ago, I got my Mixtrack Pro, and within a month I was rocking house parties with my little hi-fi system. Now I’m on an S4/F1/Maschine.
As for day one, a Mixtrack Pro was so intuitive, that (with the help of sync back then) VDJ was a breeze to get started with. I still break it out on occasion, and just use the S4’s sound card.
