Reply to Complete newbie help....

Hi this is my 1st post on here so excuse the complete newbie but I appreciate the help in advance to you all!

#I've just started using Traktor pro on my mac for the last few months and looking to gradually get myself building up knowledge and gear but baby steps at 1st for me. My main thing is controlling Traktor via a midi controller at 1st (a behringer bcr2000 is something a friend is selling on). Gradually from there I can get to grips with adding more. My question is to all you experts is if im using 4 decks on traktor will I require an audio 8 interface to get my sound to speakers and and headphones?

Small set up compared to the most of you I know but I have to start somewhere I guess

Thanks
