Thank you all for your efforts! I really didn't expect others here to be interested in a carillon, and I appreciate it.

I'm going to Mark this Resolved since I've received some info from the head of their tech support.

I have to say, it differs from some of what was posted here (not your fault, of course).

And, I haven't been able to return to do more testing yet. Once I do, I'll make another post to try to close the loop.

etcjoe, can you tell me where you found the info you quoted in your first post?

In general, they claim there is no User Manual because they market it as being so easy to use on the console itself. Nonsense. There is a lot of technical info and I had to dig for it.

The answer to a question as simple as "what is the type of connection for a monitor speaker in the same room as the console", is unknown without removing the back panel. Answer: XLR line-level output.

My source said, use MIDI Type 0. That alone may account for why my test files didn't work; I assumed MIDI Type 1.

They didn't know anything about a SYSEX file or any kind of info required to be in the MIDI file. Total news to them. That's why I want to find out where the material etcjoe quoted came from.

My source also told me the carillon plays MP3 files. That's a surprise. I found this out when I asked if there were built-in test-tone files so I could verify if our 40-year old speakers are blown (I'm pretty sure they are). He suggested I make my own test file as an MP3.
