Posting this for my bestie who doesn't have reddit!:
Hey not sure if anyone else had had this issue, I just got these decks and am having issues with my effects working when using reckordbox with my macbook and speakers. Songs are coming thru fine, I'm not using plug in speakers just thru my laptop, but for some reason the effects aren't working? Any help would be appreciated since I have a gig in a couple weeks.
