Every time you start the Komplete Kontrol software with a Kontrol MK3 keyboard connected, the software checks for available firmware updates and informs you if a new version is available.
Here's how to update the firmware:
1. Disable sleep mode on your computer:
On macOS, open System Settings > Battery and set Low Power Mode to Never.
If you are using a Mac desktop computer, open System Settings > Energy Saver. Disable the option Put hard disk to sleep...
On Windows, click the Windows Start Button, type "power sleep" and hit enter. Set all options to Never:
2. Disconnect any USB devices that are not needed for the firmware update, e.g. your audio interface, other audio controllers, etc.
3. Make sure the Kontrol MK3 is connected and turned on.
4. Download the KSMK3 Updater here:

5. Close your web browser and all other applications.
6. Unzip the downloaded file and run the extracted "Updater" application.
7. If prompted, allow the connection.
8. The updater shows the Installed Firmware version and the Newest Firmware version. Click the UPDATE button.
8. The firmware of your keyboard is now being updated.
IMPORTANT: Do not let the computer go to sleep or unplug the device during the update process! If you are using a power supply, do not unplug it!
This process can take several minutes. Please be patient and wait until the process is complete!
