Just a warning to my fellow travelers -- when doing games with microphone input, be sure your HVAC system isn't running, as the noise can distort the input. I was getting some really weird results on Melody Jay. Sure, I might waver in pitch by a semitone or so sometimes, but there was no way I was off by a 5th or a 7th like it was telling me sometimes. So I waited until the HVAC shut off, played again, and had no such problems (just those occasional wavering by a semitone problems).
