Let's keep our eye on the ball here: I've talked to people who have built carillons. Twice. You've got a hitlist. ;-) Any chance you could record some of this? 'cuz that would be amazing to hear. Not as amazing as hearing it in person for painfully obvious acoustical reasons but still... Damn - anyone ever done a surround or ambisonic recording of a carillon?
PZM means "Pressure Zone Microphone"(microphone - yeah). Their pattern is "everything" and they only work on a boundary. If you wanted to hear what the carillon sounds like inside the carillon that's the way to go. If you wanted to get the sound inside where you play it, that's a great way to do it. Generally you want to get the sound of the acoustic space where people are hearing the performance. With the massive church organs, the answer is obviously "inside the church." But hey. Take what you can get.
I'll do my best when I'm abroad--those recordings will probably be mediocre. Hopefully soon I have some nice recordings from my home tower. We've got a mic (maybe two, i.e. stereo? not sure) in the belfry, positioned to get higher quality recordings. It'd be dope to do a surround recording. But we have a small budget.
