Hi, I am currently a mobile DJ that plays at local bars, looking to provide the ability to do karaoke as well if it isnt that much more than signing up to an online web library that shows the songs on a screen etc. My question is if that does exist and if someone does this with the Traktor S4 M2 setup? What karaoke software do you use and how do you set the mics up etc? Buying advice on Mics and setup would be awesome. I am just looking to make myself more flexible for gigs.
