Native Instruments Komplete Kontrol S49 MK2

Firmware updates are delivered via the Komplete Kontrol desktop application. Connect via USB; the app will automatically prompt for updates when a newer version is available. A standalone Firmware Updater ZIP can also be downloaded from the NI Drivers & Other Files page; unzip and run the KKS_MK2_Firmware_Updater executable. Do not disconnect the keyboard or let the computer sleep during the update.
