  • Nexus (by reFX) historically used eLicenser (by Steinberg) for copy protection before moving to their own Cloud/System. Version 2.2.1 would have used the classic USB or Soft-eLicenser.
  • AIR (AIR Music Technology) uses a different system (often in-app or serial-based). There is no "AIR eLicenser" officially—this may be a misinterpretation of a cracked/custom patched version name.
