That is exactly how I started. I had very little extra cash to spend on DJ equipment. So I picked up a cheap pair of headphones, bought the home edition of VDJ, and picked up a two channel Native Instrument sound card (The Audio 2 DJ). It is not the most optimal set up, but hey it got me started. I also learned how to use CD decks/ CDJ’s as well. My first live gig the venue had house CD decks and not wanting to mix on just my laptop live, I played on CD’s for a year while I saved up for my controller. Use the time to review the controller you will eventually want to buy. It’s quite a large investment and a pretty big decision for your career. After reading many reviews and analyzing what each controller does (even the placement of the buttons, knobs, and jogs were an important factor to me) I had my heart set on the Traktor S4. Don’t be tempted to buy a controller you don’t really want but is in your price range. It may be a quick fix now, but you will end up regretting it later on.
