there is any way to convert memory cue to hot cue in Rekordbox dj ?
Where is the memory cue coming from? Traktor? Or are you just talking about modifying rekordbox cues using Rekord Buddy?
Memory cue coming again from Rekordbox and to be able to make them Hot cues in Rekordbox
Currently there is no way that I know of to do that in rekordbox.
Also currently, rekord Buddy doesn’t have cue point editing functionality so it just copies the data as is.
There are thing planned for the future but I can’t give you a date as to when this would be available.
Or there is any way to convert memory cues from Rekordbox to Traktor as hot cues with Rekordbuddy?
Not currently. The two conversion options are one to copy hotcues to memory cues when copying to rekordbox and the other one to copy memory cue to hotcues when copying to Serato. The manual (which you can find in the Help menu) describes all the options available in the current version.
