I'm not 100% sure this will work as I havent got the free xmas metaphysical function but I had problems assigning the X/Y faders in the Electronic Instruments 2 version to my Remote SL. I think what might be happening with the midi learn is when you move a fader/knob on your controller, it is changing the X axis and not the Y. its the Y axis you need to change for metaphysical to respond to changes on your controller and I couldnt find a way of doing this. I had to go into the properties of the X/Y faders and change all the Y axis controller numbers manually.
Hopefully this will work for you.
