Software sampler instruments come in many different flavors and formats. The “SF2” file extension represents a Soundfont file – a file format created by Emu Systems in the early 1990s and most commonly associated with products designed by Creative Labs. The “NKI” extension is a file format Native Instruments uses to denote sampler instrument files compatible with the Native Instruments Kontakt software sampler. Getting your Soundfont files into NKI format is as simple as taking advantage of Kontakt’s native Soundfont-import capability. Warnings Writer Bio
