Convert REX to NKI

Understanding REX and NKI file formats

REX files are audio loop files created by Propellerhead ReCycle, widely used for slicing and tempo-matching loops in music production. These files contain audio data along with slice information, making them ideal for use in digital audio workstations (DAWs) and samplers.

NKI files are instrument files used by Native Instruments Kontakt, a popular software sampler. An NKI file contains instrument settings, mappings, and references to audio samples, allowing users to play and manipulate sampled instruments within Kontakt.

Why convert REX to NKI?

Converting REX to NKI allows producers to use sliced loops from ReCycle directly as playable instruments in Kontakt. This enables advanced manipulation, layering, and integration into complex sample-based compositions.

How to convert REX to NKI

There is no direct, one-click converter for REX to NKI, but the process can be accomplished using a combination of software tools:

1. Export slices from ReCycle: Open your REX file in ReCycle. Use File → Export and choose WAV as the format, ensuring you export all slices as individual WAV files.
2. Create a new instrument in Kontakt: Open Kontakt and create a new instrument (File → New Instrument).
3. Map the slices: Drag and drop the exported WAV slices into Kontakt’s mapping editor. Assign each slice to a key or zone as desired.
4. Save as NKI: Once mapping is complete, save your instrument using File → Save As and select the NKI format.

Best software for REX to NKI conversion

• Propellerhead ReCycle – for exporting REX slices as WAV files.
• Native Instruments Kontakt – for creating and saving NKI instruments.
• Chicken Systems Translator – a commercial tool that can automate some aspects of converting REX files to Kontakt instruments, streamlining the process.

Tips for a smooth conversion

• Ensure all slices are exported at the correct sample rate and bit depth for Kontakt compatibility.
• Organize your exported WAV files for easy mapping in Kontakt.
• Consider using batch mapping features in Kontakt to speed up the process.
