How Does Traktor Work? There are several versions of Traktor, the most popular being the Traktor Pro, which comes with an interface and two-tone records. Here's how it works: The audio files on a computer or external hard drive will be transposed onto the tone records. The tone records are calibrated so that when the pitch is adjusted on either turntable, the music that is being played will adjust accordingly. Note: Traktor does not come with turntables. Why Use Traktor? Instead of dragging crates of records from gig to gig, all that's is needed is a computer or a hard drive. Also, the visual aid is a benefit when a DJs are mixing or beat matching. Traktor also comes with some tools that make looping easy as well as some basic effects processing software like flanger, phaser, delay, etc. Most DJs prefer to use Traktor with their turntables for the authentic analog feel and ability to manipulate just like regular vinyl. Note: If this is how it is going to be used, it is necessary to have a mixer and two turntables. And everything you need to know: http://www.djworx.com/skratchworx/revie ... cratch.php
