Yea. I think it’s your software. Preset behaves fine here.I was looking at the front screen meters. even with no preset loaded, usb channels 5 and 6 are active (because they are the default DI reamp tracks) and for some weird reason, all of the video making programs ive found don't have a setting to turn those off. i can do it just fine in reaper.
Try setting your audio properties in the video software to stereo. I think it’s interpretating the extra channels as surround input channels.
