So why do I see the Melody on Channel #3 when it should be on Channel #4??
Or a better question, Who put a -1 in this hidden option? And could it only be Build 825?
It's in 822 ... I've not long (an hour or so) found the hidden option and I'd changed that from -1 to -2, thinking that might change my channel 6 to channel four. It appeared not to do so, but might be implicated in the later change 6->4. I'm still puzzled why I see(saw) channel 6 when you see channel 3.
I've wondered if the -1 is for interpreting the channel 0..15 versus channel 1..16 conundrum.
