| hehe, well, mainly it's done this way for full flexibility (you define
a separate panning curve for each channel transition),
one configuration that I commonly use is to route output 1 and 2 to
dry left and right, then use the other outputs for effects (that end
up panned somewhere in the stereo field as well), in this case equal
power routing between the different effect sends may not be desirable.
