Hello.I need an audio interface so I can connect Traktor’s four decks to an external 4 channels mixer so I can control them through the mixer .Motu UltraLite MK5 is one interface that I m thinking of bying .Another one is the Focusrite Scarlett 18i20 3rd Gen .Has anyone use any of those two with Traktor?If yes ,are u satisfying with?Any other suggestion?I think I prefer the Motu cause its smaller and It looks qualitatively better
