Hey all! I'm hosting an ugly sweater Christmas party next month and want to bring my desktop out to the living room with two Rock Band mics hooked up to my 46" flatscreen via HDMI. Looking for the best karaoke program with a one or two day pass that I can purchase for a good price. It can be on Windows 7 or OS X Mountain Lion - I am running both on my machine. I also have 5.1 surround sound speakers. So far, I downloaded KaraFun to see what it's like. Pretty simple service - access to 13,000 songs for $5.99 for two days, or $9.99/month. I just want to ensure that the program supports 2 mic inputs. All ideas welcome!
