it's backwards in a "numerical" sense,

However, UI designers don't think in numbers, but associations.
Left is generally associated with up, right with down, as we read left to
right, top to bottom. Therefore, up MUST map to left, down MUST map to
right, otherwise, non-mathematically minded people get uttely confused.
OK, if things 'increase' from L to R and from top to bottom,
then a vertical gain slider should have the 'off' position at
the top. For a slider controlling a frequency, the lowest
one should be at the top.
I suspect most people would find that counterintuitive,
regardless of reading directions.
