@Ricardo - Yes, you have to connect the NanoKontrol to a PC in order to change which CC’s are sent. I had some issues getting the Korg Control Editor software running correctly on my PC due to KORG MIDI Driver 
.
There are also different start up modes for the nanokontrol, which still confuse me and I haven’t got used to it 
. see the manual for details of these modes.
All that being said, for the most part, normal start-up and Instruments that support MIDI Learn work fine on Cubasis/iOS through the Camera Connection Kit.
@@@@@@Ricardo - It would be nice if we could use the nanokontrol with the mixer and transport controls
