Real memory cues do not exist in Lexicon. Lexicon only has regular cues, but you can mark them as Memory Cue so they become memory cues only in Rekordbox.
Memory cues is something that only exists in Rekordbox. You can send your Lexicon cues to the Rekordbox memory cue bank though. On the Sync page, choose "All to memory cue" in the "Cue Destination" option.
To mark an individual cue as memory cue, enable the "DJ app specific feature" first in the Lexion settings. Then you can click the little "M" button on the cues. If you set a cue as memory cue, it acts as normal cue in Lexicon (and DJ apps you sync to) but for Rekordbox only, that cue becomes a memory cue. You need the "Cue Destination" on Default for this.
