Convert REX to WAV

It shouldn't be too complicated trying to convert ReCycle Loop Files directly to WAVE Audio Files (.rex to .wav conversion), since certain dedicated tools support such efforts.

You can use the original software, ReCycle, a program for fast editing of sampled parts, chopping up riffs, remixing and doing mash ups.

But you can also try using some third-party alternatives, such as Translator 7 or Avid Pro Tools, which will allow you to import REX loop files and export them in various audio formats, including WAV.
