I bought a Vestax Typhoon to learn the basics of DJing knowing that I would have to upgrade my gear if DJing worked out for me. I am getting ready to get a pair of Numark NDX900s but I am not sure what mixer should get. I am afraid that if I get a two-channel mixer, I will want to upgrade it to a four-channel mixer. I only plan on using two decks but it seems like a lot of people still have four-channel mixers. In your opinion, is it important to have a mixer with more than two channels and why?
And if I plan on using the NDX900s to control Virtual DJ, will I need a USB mixer? (The NDX900s have MIDI capability)
