Free online SXT to WAV converter

Some samplers and audio workflows need a rendered WAV rather than an SXT instrument patch. Converting the patch requires rendering notes through a compatible sampler; an SXT file does not define one finished piece of audio.

What the SXT format is

SXT is the patch format used by Propellerhead Reason’s NN-XT sampler (now part of Reason Studios Reason). It stores instrument settings and sample key mappings, and may refer to sample files stored separately. You typically encounter it in Reason projects or sample libraries.

What the WAV format is

WAV is a widely supported audio container, commonly used for uncompressed PCM recordings. A WAV render can be imported into audio editors, video software, and devices that do not load sampler patches; its uncompressed audio is also convenient for editing.

How to convert SXT to WAV

Online on 101convert.com

1. Open the SXT-to-WAV converter on 101convert.com and upload the SXT file.
2. Start the conversion, then download the resulting WAV file.

The page supports batch conversion and displays a per-file size limit.

Offline with desktop software

In Reason for Windows or macOS, load the patch into an NN-XT device using its patch browser, then create a MIDI clip on the NN-XT track and add the notes you want rendered. The notes determine the pitches and duration in the output; play the song to check the patch, then choose File → Export Song, select WAV, and set the desired sample rate and bit depth in the export options.

Quality and limitations

An SXT patch is an instrument definition, not a single recording, so the WAV depends on the MIDI notes, their duration, the patch settings, and whether its referenced samples are available. If Reason reports missing samples, locate or relink them before exporting; otherwise the render may be incomplete or silent.
