This is how you would use your PC to be a DJ if you are disabled. First you'll need a second sound card option for the headphones. Cheaper headphones can be used also until you're able to get the proper ones. The software you will be using supports microphone input which is called Virtual DJ. It's a fantastic kit made especially someone with a disability with all the same things that you would find in other decks and a mixers. Then you would want to just experiment with the controls until you get the hang of what's going on. Most important never let anything stop you from ambitions and dreams that you may have.
