When PFL is activated for an empty on-air channel TurboPlayer picks out the element for prelistening normally (or one of its successors if the element is already running). This is the standard behavior which can be achieved with the setting "Next" or without defining this parameter. TurboPlayer can also prelisten one of the cursor elements. Each GUI has its own cursor but the mixer console exists only once. Therefore you must define which GUI/cursor is used for the selection of the prelisten element. Set this parameter to "CursorX" where X is the desired GUI number.
