Working with loops and Groove Clips
Working with Groove Clip audio
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” on page 638).
To import a REX file
1. On the File menu, point to Import and click Audio.
The Import Audio dialog 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” on page 763 and “Freeze tracks and synths” on page 829.
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:
• Enable Looping
• Beats in Clip
• Enable Stretching
• Marker tools
• Slice Resolution
• Transient Detection
