Hi Guys, New to Sonar X3 and trying to follow instructions to define a new groove, without much luck. Can someone point me in the right direction?

I follow the instructions below (I select 4 bars of Drum Audio, copy to the Clipboard, Process Groove Quantize) but there is no option to select "clipboard" as the "Groove File" & "Define" is greyed out. What am I doing wrong?

(From Help File)
To define a new groove 1. Select the music that defines the groove using any of the selection tools and commands.

2. Choose Edit > Copy to place the music onto the Clipboard.

You can now use the Groove Quantize command with the Clipboard as the “Groove File.” To save a groove pattern 1. Select the music that defines the groove using any of the selection tools and commands.

2. Choose Edit > Copy to place the music onto the Clipboard.

3. Choose Process > Groove Quantize to display the Groove Quantize dialog box.

4. Choose the Clipboard as the groove “Groove File.”

5. Click the Define button to display the Define Groove dialog box.
