the Quadrabell tape driven carillon video

I saw a video on the internet that was about the Quadrabell tape driven carillon. I would've done anything to find something like this out, as I was once very curious on how those bells were rung to play those songs on such a tiny steeple. Chances are the guy that made this video worked at this church, as you heard the beautiful bell songs played on the carillon as he walked toward the side of the church. The church seems to be a Zion church as it said on the sign at the church. The guy went to the side of the church, into some doors to get inside and up a flight of stairs. As he goes upstairs, you hear the bell music getting louder and louder, until he reached the top of the steps and you saw the Quadrabell  tape deck carillon in full operation. I have to say that although it's a tape driven carillon, the bell music sounds really good and memorable. It was really neat to see this video, as I now know that churches have those type of carillons to play their songs, but I would've loved to see their device and where it was placed. Most times I got  yelled at by someone who worked at the church when I asked about their bells. Were they trying to keep it a big secret, or was this something that they were only supposed to know? There is nothing wrong with asking about something you want to know about, since I was very interested in their bell songs and I wanted to say how much I appreciated them. I figured that if I knew what electronic carillon system the church had, I could look it up on the internet and find out more info on it, and maybe get some song samples. I'm sure I wasn't the only one curious about the church bells and how they were rung.
