Reason’s NN-XT sampler uses SXT patches, so an SF2 SoundFont may need conversion before it can be used as a native NN-XT patch. Converting preserves an instrument’s sample zones and settings as a patch rather than rendering the instrument to a single audio file.
What the SF2 format is
SF2 is the SoundFont 2 format: a file can contain sampled instruments, presets, key and velocity zones, and synthesis parameters. SoundFont editors such as Polyphone create or edit SF2 files, which are also used by software synthesizers and samplers that support SoundFont banks.
What the SXT format is
SXT is the patch format for Reason’s NN-XT sampler. It stores an instrument setup, including sample assignments and zone settings, for use in Reason. Convert to SXT when you need an NN-XT patch; it is not a replacement for a rendered WAV or other audio file.
Convert online on 101convert.com
- Open the SF2-to-SXT converter on 101convert.com and upload the SF2 file. The page shows the per-file size limit.
- Choose SXT as the output format if prompted, then start the conversion. You can submit several files as a batch.
- Download the converted SXT file or files.
Convert offline with desktop software
Reason is the direct desktop option: its NN-XT sampler can load SoundFont files and save patches in SXT format. Create or open an NN-XT device, load the SF2 through its file browser, then use NN-XT’s Save Patch control to save the instrument as an .sxt file. Reason runs on Windows and macOS.
Quality and compatibility
SXT preserves a sampler patch, not the original SF2 container or a guaranteed bit-for-bit equivalent. Check the converted patch in NN-XT: SoundFont modulation, preset layering, or other parameters may not map exactly, and a patch that refers to external samples may require those samples to remain available.
