I am not sure I follow? Do you want to test that you have correctly patched the PA system? This to me is as simple as hard panning or sending the media to the desired buss/mix. If I have a stereo track I simply pan both to one side to confirm correct patch of the PA system. For monitor mixes and other things like side fills, center fills and delays, I just send a signal out and confirm.
I am not stuck on the whole " I play this song and I know it so well " that I can tune a PA to it mantra. If it sounds right it is right, doesn't matter what song it is or how well you know it. That being said I do listen to a variety of songs in which I am well aware of the genre and expected sonic content. Any modern pop song will pretty much give you a good idea of where you are sitting though. My feeling is that there is always an idea of what your favorite song should sound like. Familiar with it or not, it does not make your PA tunes any more consistent. If you really need consistency and bias confirmation, you have to resort to Smaart or some other tuning software.
I do agree that using a DAW such as Audacity or Reaper ( I LOVE Reaper !!!!! ) can pretty much allow you to make any track you wish and design it to do anything you need.
