Convert NKM to SFZ

Understanding the nkm and sfz file formats

NKM files are Native Instruments Kontakt Multi files. They store multi-instrument setups, including instrument assignments, effects, and routing, for use within the Kontakt sampler. These files are proprietary and are only compatible with Native Instruments Kontakt software.

SFZ files are SFZ format instrument definition files. SFZ is an open standard for defining how audio samples are mapped and played back in software samplers. SFZ files are widely supported by various samplers, such as Sforzando, ARIA Player, and others.

Why convert nkm to sfz?

Converting NKM to SFZ allows you to use your Kontakt multi-instrument setups in a broader range of samplers that support the open SFZ format. This is useful for sharing instruments or moving away from proprietary software.

How to convert nkm to sfz

There is no direct automatic converter for NKM to SFZ due to the proprietary nature of NKM files and the differences in how instrument data is stored. However, you can perform a manual conversion by following these steps:

1. Open your NKM file in Native Instruments Kontakt.
2. For each instrument in the multi, File → Save as... to export the instrument as an NKI file and collect all used samples.
3. Extract the sample files used by each instrument.
4. Create a new SFZ file using a text editor, mapping the samples according to the original instrument's key and velocity ranges.
5. Test the SFZ file in a compatible sampler (such as Plogue Sforzando).

This process can be time-consuming, especially for complex multis, but it is currently the only reliable method.

Recommended software for conversion

• Native Instruments Kontakt – Required to open and extract data from NKM files.
• Plogue Sforzando – Free SFZ player for testing your converted instruments.
• SFZed (Windows) or Polyphone (cross-platform) – Useful for editing and creating SFZ files.

Summary

While there is no direct NKM to SFZ converter, you can manually recreate your Kontakt multis in the SFZ format by exporting samples and writing SFZ mappings. This allows for greater compatibility and flexibility across different samplers.
