Working with REX files

SONAR supports two types of Groove Clips:

ACIDized Groove Clip

REX-based Groove Clip

Like ACIDized WAVE files, REX files are audio files that are designed to be looped and follow the project’s tempo. The time stretching technology that REX files use is well suited for percussive sounds, such as drums.

You can import REX files into a SONAR project. Once imported, you can work with REX files just as if they were regular Groove Clips (see Working with Groove Clip audio).

Note: REX-based Groove Clips can be edited in the Loop Construction view, but certain Loop Construction view tools only apply to ACIDized Groove Clips. The following Loop Construction view commands, settings and tools do not apply to REX files: 4 Enable Looping 4 Beats in Clip 4 Enable Stretching 4 Marker tools 4 Slice Resolution 4 Transient Detection

To import a REX file

1.	On the File menu, point to Import and click Audio.

The Import Audio dialog box appears.

2.	In the Files of type list, select All Audio or REX (*.rex, *.rx2, *.rcy).

3.	Find and select the REX file you want to import.

If you want to preview the selected file, click Play. The file will play at the current project tempo.

4.	Click Open.

The REX file is imported into SONAR as a Groove Clip.

You can also drag REX files into SONAR, paste from the Clipboard, or import from the Media Browser view.

To disable looping of a REX-based Groove Clip

If you want to disable looping of REX based Groove Clips, use the Track view Clips > Bounce to Clip(s) command or click the track’s Freeze button render the REX based Groove Clip to a standard audio clip.

For details, see Bouncing to clips and Freeze tracks and synths.

To use pitch markers with REX-based Groove Clips

Unlike ACIDized audio loops, REX files do not store the original pitch (root note) value. If you want a pitched REX file to properly follow your project’s pitch markers, you must manually specify the original root note for each REX clip. By default, SONAR assigns a root note value of G#.

Due to limitations of the REX file format, the root note value can not be saved back to the REX file, and must be manually specified each time you import a REX file into a SONAR project. If you want to permanently save the root note value with a REX loop, export the REX Groove clip as an ACIDized .wav file.

For details, see Root Note and Saving Groove Clips as Wave files/ACIDized Wave files.
