Couplings The state of Auto Initialize is not affected by "Auto Couple" on page 2017
Auto Initialize is set to ON by Preset or All Markers Off
If Auto Initialize is ON for a marker and that marker is on, that marker’s Marker Trace is immediately set
according to the above flowchart
Sending the remote command causes the addressed marker to become selected

When the marker moves between traces the marker’s X position in trace points is
retained as it moves. For moving between active traces this generally means the x-
axis value of the marker does not change. But for moving to or from an inactive
trace, the x-axis value takes on that of the new trace at the bucket the marker was
on the old trace (and is still on, on the new trace, since the bucket doesn’t change).
Note this is true even if the marker is off screen. Thus, a marker that is at the center
of the screen on the old trace stays at the center of the screen on the new trace. A
marker that is off screen one whole screen to the left on the old trace remains off
screen one whole screen to the left on the new trace – even if this means it is at
negative time!
