Becoming an NN-XT developer

We are happy that you are interested in building software supporting the NN-XT patch file format. Below you will find all information you need to proceed.

About the file format

The NN-XT is the advanced sampler device included in Propellerhead Software’s Reason software. If you’re not familiar with the NN-XT, we recommend that you download a demo version of Reason from our web site and try it out.

Briefly, an NN-XT patch file contains the following information:

  • References to samples, supporting a number of audio file formats, sample rates and resolutions.
  • Sample parameters, such as play (loop) mode, sample start/end, root note, etc.
  • Key range and velocity range information for each sample, allowing for multi-sampled sounds, layers, velocity switching and crossfades.
  • Individual synth parameter settings for each sample.
  • Routing information for each sample (the NN-XT has eight individual audio outputs).

Who can become a developer?

Anyone can register as an NN-XT developer, including private persons. There are no costs involved. Propellerhead Software will administer the authorization, copyrights, logos, and trademarks. We’ll also provide technical support, free of charge.
