My premise is that it’s just a midi controller and each button, slider, knob generates values that correspond to actions in Logic.
The nanoKONTROL is a basic MIDI controller with an Editor. That's it.
If it works, it is a small cheap helper tool.
But Korg tells you to install the control surface software to transform the nanoKONTROL to a fully-fledged DAW controller. This is ridiculous, but most people follow the advice after reading Korg's bold words.
A control surface software translates device events (nanoKONTROL) to control events (Logic) and vice versa and mostly uses an existing protocol like Mackie, Logic Control, Mackie HUI etc. This is what you see in Logic's control surface setup. You find all mappings in Logic's Controller Assignments and everything gets stored in the .cs file which occasionally gets damaged. Keep a backup of this file if your custom mappings are important to you.
Finally, when it becomes apparent that this little plastic plate does not make a good DAW controller, you can delete the icon in the setup and delete the associated software piece or move it to another location. It is a good idea to delete the .cs file also, just in case Logic does not handle the zombie data correctly.
Now you got your MIDI controller back, in the Korg editor you can set numbers for knobs, buttons and faders and then work directly with Logic as usual. Assign events to parameters and functions as you like. Keep some
MIDI CC list around to check if a number you want to map could do something you don't want, when it is
not already mapped. For example, rather avoid CC numbers 0, 1, 7, 10, 11, 32, 64.
So much to the usage, but we also have to deal with Korg. The first generation nanoKONTROL just stopped working, no update, you were expected to buy a new one. I had also also a little keyboard which stopped working. No update, you were expected to buy a new one. We all know that Korg can also make good stuff, so what can we learn? Probably that we should not believe marketing speech and for long-time happiness we should not buy a Korg device that weighs under 15 pounds ;-)
