Are the nanoKontrol2 knobs mapped to anything in Sunday Keys for Ableton?

No, we have chosen to leave the knobs on the Korg nanoKontrol2 midi controller un-mapped in Sunday Keys for Ableton so you can map them to the function that makes sense to you. 

Check out this video from the Sunday Keys Resource Page under 6. Setting Up Midi Controllers - "Control Sunday Keys with the Korg nanoKontrol 2" to learn how we have it set up:

Check out this video to learn how to midi map any of the knobs that is un-mapped by default:

You can also follow these steps to map a control, keep in mind that only controls (knobs, faders, buttons, etc...) that send midi can be mapped, so you may want to double check your user manual:

1. Make sure your nanoKontrol2 (or other controller) is connected to your computer. 
2. Open Ableton Live > Preferences > Midi - It should show your controller in the list. Make sure Track and Sync are turned off for the nanoKontrol2, and Remote is turned on. If it's off, click on it to turn it on or vice versa as needed. Now, close Preferences.
3. You can midi map to basically anything. Click the "MIDI" button on the top right corner of Ableton.
     
   Now, click the control in Ableton that you want to connect your hardware control to - like one of the instrument macros for example. Now, move the physical control and if the mapping was successful, you should see the numbers on that macro change as you move your physical control. Click on the "MIDI" button to turn it off. Try moving that physical control again to see if the mapping was successful and does as you would expect, changing the sound.
