Native Instruments Komplete Audio 2

No updatable firmware on the Native Instruments Komplete Audio 2

It is analog or fixed-function hardware, so there is nothing to update.

You can still add it to your rig to keep an inventory and track its used market price.

If a firmware update is available, download the Device Updater ZIP from the Native Instruments Drivers & Other Files page. Extract and run DeviceUpdater.exe (Windows) or DeviceUpdater.app (Mac) with the device connected via USB. Do not disconnect during update. On Mac the interface is class-compliant; on Windows install the ASIO driver separately.
