492 Chapter 21 Editing Audio in the Sample Editor
Absolute and Relative Time
The different axis scales in the Sample Editor can be displayed in two ways:
 By reference to the time axis of the project (absolute position)
 By reference to the beginning of the audio file (relative position)
The units in the ruler (between the overview and the waveform display) are displayed
with dotted lines when viewing the relative position.
To enter the relative display mode, do one of the following:
m Open the Sample Editor from the Audio Bin.
m Activate Link mode in the Sample Editor, and select a region in the Audio Bin.
The beginning of the section is automatically assigned to the zero value, or in bar/beat
terms, position: 1 1 1 1. The position marker lines are dotted, indicating no time
connection exists.
Note: This will not necessarily match the actual playhead position. The calculation of all
remaining musical sections uses the current project tempo at corresponding positions.
To enter the absolute display mode, do one of the following:
m Open the Sample Editor from the Arrange window.
