Extract text from Kontakt audio banks (NKB)
To convert NKB audio banks to another format, you need Kontakt or other Audio software.
To convert other file formats to the "Sampler Bank File" file type, you need software like Kontakt or a similar tool.
A .NKB file is a proprietary Kontakt Audio Bank created and utilized by Native Instruments Kontakt. It functions as a specialized container that groups up to 128 individual Kontakt Instruments (NKI files) together, allowing musicians to switch between different sounds instantly using standard MIDI Program Change messages during a live performance or studio session.
The main disadvantage of the .NKB format is its heavily closed, proprietary nature. It requires an expensive commercial license for the full version of Kontakt to edit or fully access the internal routing, KSP (Kontakt Script Processor) scripts, and layered samples. Furthermore, because it is a complex database of synthesis rules and compressed audio, standard media players and generic online audio converters fail to process it entirely.
Users often need to convert .NKB files to open sampler formats like SFZ (SoundFont), SF2, or EXS (Logic Pro EXS24) to use their purchased or custom sound libraries in alternative Digital Audio Workstations (DAWs) without being locked into the Native Instruments ecosystem. However, due to the complex architecture, only the original software can properly read or export all the intricate modulation data. Specialized third-party tools can extract basic velocity layers and raw samples, but advanced scripting is always lost during the transition.
This closed format is notoriously difficult to open or convert externally.
Convert.Guru analyzes your NKB file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NKB converter.
