Just wondering what sound card people use? Do you use the built in sound on your Mac or do you use an external audio interface? I currently have an external steinberg USB2.0 audio interface but not really utilising it that much - collecting dust. I occasionally tinker with Logic Pro X but am not a full time musician. If I do anything on there is just soft synths and samplers. Not recoding any external vocals or instruments into it. How does Logic Pro X cope with Internal Core Audio on a Mac Mini 2012 i7 with 16GB Ram compared to a USB audio interface??
