All I want to do is transfer 2-4 measure loops to my Mac so I can import them as audio files into Logic. I'm tired of trying to use the Machine + as a standalone unit (most exasperating piece of gear I've ever tried to learn). I watched the MacPro Video tutorial and succeeded one time in getting the SD card to appear on the desktop of my computer but never found the audio file that I thought was stored there. So I tried again (and again and again) and now I don't see the SD card on the desktop at all. I've restarted both the Maschine and my computer several times and no cigar. Can anyone help me?
