To create a cycle from a marker, do one of the following:
m Drag a marker up into the top third of the Bar ruler.
This will set a cycle with the same position and length as the marker. If Logic Pro is
stopped when performing this action, the playhead will be placed at the start point of
the cycle.
m Select the marker, then use one of the following key commands:
 Set Locators by Marker and Enable Cycle
 Set Locators by Previous Marker and Enable Cycle
 Set Locators by Next Marker and Enable Cycle
Customizing the Marker Display in the Marker List
There are two display options for marker position and length in the Marker List:
 View > Event Position and Length in SMPTE Units: Switches the marker position and
length display between bar positions and SMPTE time positions.
 View > Length as Absolute Position: Switches the marker length display between
actual (relative) length and (absolute) display of the marker’s end position (shown as
a bar position).
