wow .. well do you plan on using controllers or actual tables with vinyls… theres a lot! of researching to be done wheather you know what u want or not….. If i were you id go to guitarcenter.com and look at different tables/ controllers to see what you want and what is in your price range.. or possible head out to a local music store (guitar center) and ask a professional and talk to them about what you like what you will be doing and what youd like to do in the future.. they are very helpful and typically get you going on what you want and need ,, even within a decent price range….
here are some other tips aswell!!
1. Depending on the type of Turntable it might or might not come with Vinyls that are specifically made for it.. Some programs such as Traktor come with Vinyl to put on your Turntable..
2.Most djs that take their Laptops with them is because their music library is all on there.. They connect their turntables to the Computer to load the track into each deck (turntable).. They use the vinyls mainly for scratching, ff , beatmatching, and sometimes as a jogwheel.. They vinyls are not mainly used for just playing the track…
3. Having 2 turntables is a main helper because A. you can have one track playing for everyone and in the other table your listenin with your eadphones to match the beat with the other track and get ready to mix the songs together. B.you can play the track from one table and scratch a sample or song from the other turntable. Using the crossfader to mix the tracks back and forth..
4. You don’t necessarily have to use a program with djing but its more often then not that whoever is djing has a computer with Traktor, Reason, Ableton Live, or some other program especially if whoever is djing is using a “Controller” such as the “VCI-100″ rather than turntables such as a “Pioneer”..
