Technical minded people may have trouble figuring out how to enable their USB MIDI Controllers to interact with the Native Instruments suite of tools. Many of the packages included in the Komplete bundle install with the midi settings turned ‘off’.
The simplicity of getting your controller to work with any of these apps is confused by the non standard interface which the Native Instrument team has implemented for turning on/off the MIDI inputs.
The MIDI settings window is not just an informational screen, it’s actually functional. It just doesn’t appear to be.
To enable your MIDI controller:
1) Go to ‘Audio and MIDI settings’ option from the menu
2) Select ‘MIDI’

3) Under the ‘Status’ column you’ll see the current state of your connected instruments. Click the word ‘off’ (or ‘on’) related to the controller of your choice. Surprise! Although it appears to be only informational, the status indicator is actually a drop down menu that will allow you to toggle the device ‘on’ and ‘off’.

After doing some research, it appears that this setting has been represented this way for a very long time. Don’t expect it to change any time soon, but I wish it would.
