So PMM/PMA use that "Channel-15" area regardless?

Wow, I never thought of that.

PMM/PMA use the parameter area designated for channel 15 regardless 
of which channel they are running on?

I think that would have taken me a long time to figure out. 

It would be nice if the documentation was a bit more clear on this 
point. I suspected a typo was more likely than a function that used 
parameter RAM that was designated for another channel.

Thanks again, especially for the prompt post.
