It's the weirdest thing. When I save to the desktop no problem, the mapping stays put. However when I export to the Default Settings/ Controller where all my mappings are it disappears! I made the folder called it KORG because it didn't exist and put my Korg mappings in there. Two of them that I downloaded from someone else, seem to live quite happily but mine might stay there briefly but soon it disappear. The odd thing is though I don't think it deletes it. Sometimes I can get it showing in the Device Setup of the Controller Manager. Any ideas?!
