Why does the Tracker have auto revert (AR) and non revert (NR) options?
The Tracker is equipped with an auto-revert function as well as non-revert function. In all versions of the Tracker DTS except 1997-98 and 1998-99, the default mode is non-revert. To engage auto-revert on all modern Trackers, you must press the Options button while turning the Tracker on; otherwise it will remain in non-revert mode.
