Jerry I agree with your point of view. As Beagle pointed out most of the drum software offer a way to change this only problem with XLN and AD 1/2 it is not obvious, though it can be done.
Any of the pans can be reversed and if you are not using individual outs and doing the panning within SONAR here is how it is done.
Place your mouse pointer on the the Orange bar in the middle of the pan control left click and drag downwards.
The two width bars will begin to move to the centre and then, when they meet in the centre, keep dragging and the pan control will turn blue moving out wards. Result the entire kit perspective will be reversed.
All the other pans will work in the same way.
