Hi, I am trying to stream some mixing from my technics turntables through my Saffire pro dsp24. I use a MacBook Pro 2012. I currently have sound going through the Saffire and into the Mac. I can see the levels in the Sound preferences and on the VRM for the Saffire. I have downloaded Blackhole 16ch and watched the video but still nothing. Any advice would be greatly received. I'm clearly missing something.
