Hi everyone. Perhaps someone can solve this mystery for me. Why does the output change on the bottom multiplier when the input doesn't? To test, hit the message on the left once, followed by the message on the right twice.

Its an order of operations issue. You are setting the left operand of the multiply first (which triggers output), then setting the right operand.

In this case, when you click on the 127, the left operand is set to 0. , triggering the arithmetic (0. * 0.), and then the right operand is set to 1.

In the case of clicking the 255 for the first time, the left operand is set to 1., triggering the arithmetic (1. * 1. = 1.) and then the right operand is set to 0.

When you click the 255 again, the left operand is again set to 1., triggering the arithmetic with the right operand value set last time around (1. * 0.= 0.). Then the right operand is set to 0. again.

Oh, I see it now. My brain is so used to patching audio cables - these cords that do math are quite a different animal and my brain is still making sense of it. Thanks very much for your help.
