Thank you for responding. I’m recording an acoustic guitar. It’s plugged into the Input 2 on the Yamaha interface (mic/instrument toggle set to instrument). I’m recording it on a default Acoustic Guitar track, with Input set to Mono ln2 and Output set to Stereo. The Pan is set to the middle (C). After recording, I can hear the track in my left headphone, and when I pan to the right, it goes silent - no sound from the right. I’ve tried different headphones with the same result.
