At first everything is ok functions normal than 30 pin cable is broken. I gave it to the service. When i plug it back with usb to my pc, pitch wheel functions as modulation when turn up modulation function down, turn pitch wheel down modulation functions up? Modulation wheel functions as pitch wheel. I plug it with camera connection kit to ipad 2 pitch and modulation still the same. Then i've factory reset the mobile keys now its not working on ipad, but works on pc all functions still same. What can i do?
