Hi, I’ve dabbled with SoX over the past 10 years, but now have a serious project I need help with. I want to record multiple channels from a Scarlett 18i20 interface, as you would with, say, Logic Pro. I’ve looked at several manuals and examples, and I can’t decipher how it applies to my situation. How would I record one stereo stream from, e.g., channels 1-2 of the Scarlett 18i20, then send another command to record (simultaneously) from channels 3-4 to a different file? Any help would be appreciated. Thanks!
