Click this checkbox to
turn on Data Slicing.
When Data Slicing is enabled, the realtime instruments display the data which
lies underneath the current position of the cursor. The grey area around the cur-
sor represents the range of samples currently displayed by the realtime instru-
ments. If you drag the cursor around in the overview window, the realtime in-
struments will continuously update to reflect the current cursor position. If you
replay the capture, the realtime rack will continuously update in sync with the
playback.
