No matter what I've tried. I've ensured that the tracks are mono. I've restarted both Mac and Logic many times. Opened new projects and recorded audio tracks numerous times. I'm running through a Focusrite Scarlett 18i20 and the Scarlett Mix Control app. I've checked that my monitoring setup has both channels working... when I mute L ch or R ch in Scarlett Mix Control, the speakers turn off and on as they should. But, any mono track, when I pan back and forth, whether from the Logic mixer, or the track pan knob... DOES NOTHING. Can you help?
