Convert NKM to SF2

Understanding nkm and sf2 file formats

NKM files are Native Instruments Kontakt Multi files, used by the Kontakt sampler to store multi-instrument setups, including instrument assignments, effects, and routing. These files are proprietary and specific to Kontakt.

SF2 files, or SoundFont 2 files, are a widely used format for storing sampled instrument sounds, allowing playback in various synthesizers and digital audio workstations (DAWs). SF2 is an open standard and is compatible with many music production tools.

Why convert nkm to sf2?

Converting NKM to SF2 allows you to use your Kontakt multi-instrument setups in a broader range of software and hardware that supports the SoundFont 2 format. This is especially useful for musicians and producers who want to share or use their sounds outside of Kontakt.

How to convert nkm to sf2

Direct conversion from NKM to SF2 is not straightforward, as NKM files are complex and proprietary. However, you can manually export the individual instrument samples and settings from Kontakt and then create an SF2 file using a SoundFont editor.

1. Open your NKM file in Kontakt.
2. Export each instrument's samples as WAV files using File → Export Samples.
3. Note the key mapping and velocity layers for each instrument.
4. Use a SoundFont editor such as Polyphone (free, cross-platform) to create a new SF2 file.
5. Import the exported WAV samples into Polyphone and recreate the key mapping and velocity layers.
6. Save your project as an SF2 file.

Recommended software for conversion

• Native Instruments Kontakt – for exporting samples from NKM files.
• Polyphone – a free and powerful SoundFont editor for creating SF2 files from your samples.

Summary

While there is no direct one-click converter for NKM to SF2, you can achieve the conversion by exporting samples from Kontakt and assembling them into an SF2 file using Polyphone. This process allows you to bring your Kontakt instruments into any software or hardware that supports the SoundFont 2 format.
