Does anyone know where I can find a video to show you how to IMPORT a stereo mix on WAV format to track 4. I bought a DP006 during lockdown so that I can e-mail my writing partner a stereo mix of something I am working on in my studio. He would then IMPORT to the DP006 work on his parts on tracks 1-3 then export a mix of them all individually to me so that I can put them on my Logic Pro on my Mac. I have just bought this machine but the manual seems to be more about exporting than importing. Non of the video tutorials I found on YouTube show what I am looking for. A numpty proof idiots step by step guide in plain English would be appreciated. Thanks J.O'B.
