Total List Length
Enters the length of the definition range of the control list in bits. The starting value is
always bit 0. The entire definition range is displayed, i.e. the bit scale is adapted to the
entry. If the definition range is decreased, the ramps outside the range are lost.
When used, the control list is always repeated over the length of the definition range if
the length of the data list exceeds the length of the control list.
Tip: With long control lists, it is useful to zoom the displayed area around the current
cursor position ("Zoom in").
Remote command:
{CONTROL LENGTH: ControlLength} on page 966
