Well, you don't have to shout about it :-)

Maybe we're not answering the same question:
This isn't really what we're seeing in say the Paia 9700, which is this
(again, pardon the ASCII art):
... then again forget the ASCII art, try this:

Also, aren't you forgetting a GROUND which plays in this as well?
