Yah I dunno. We had AP's a few years ago and we would still hear the whistle and the "brrrring" pixie sound I guess you call it. We hear the same noises now with tix. I have never heard a fantasmic sound but that would be cool as hell. We really never took they time to pay attention to what sound goes with what. All I know is that when it whislted we would whislte too. Fwee Foooo!
