Activating a range

In general, a range is activated by:

• Clicking on the range box below the parameter name (e.g PITCH). This puts two data entry boxes on the screen, for upper and lower limits.
• The boxes on the left are for single value upper and lower limits.
• The boxes on the right of the screen are for time-varying breakpoint files. Activate them by clicking on the box to the left of the upper or lower data entry box.
• Fill in a file name or click on Br.. to browse through your files if you have already created a breakpoint file.
• If you have not, click on E to create one with the graphic breakpoint editor. Save your new file and select it as above.

The relevant parameter then changes randomly between the upper and lower limits defined in this way.
