1. Select the midi learn button on the control window 2. Select the GUI fader you wish to map 3.

But if you've tried that and are still having trouble, then I'm not so sure and you will need to be more specific. And if you hadn't already tried that, or figured it out for yourself in the meantime, my sincere advice would be to spend some time with the manual and just getting to know ME some more because chances are, if you didn't know that, there's a lot more to this awesome program for you to discover. :)
