I'm trying to use Guitar Pro 7 for backing tracks and play over it with my guitar and to record the mixed signal back into my computer. I have the USB connected to the computer and set my computer playback to the Helix LT and computer recording to Helix LT. I have no problem recording into the computer and hearing GP7 play in my headphones via the USB1/2 monitoring. However, I am trying to set up my 1B track, which is nothing but a volume pedal, with an input of USB3/4 so that I can output the computer's audio back into the recording via Multi output (same as guitar). I hear the music in the headphones still but it the backing track is not being recorded, which leads me to think I am still only hearing it via the USB1/2 monitor rather than USB3/4 which should be recording.
Does this sound like the correct setup for what I am trying to achieve? I just ordered a 1/8 to dual 1/4" adapter on amazon as a backup plan but would prefer to get the USB working.
Also side question, if I am feeding audio from my laptop to the Helix then back to the laptop via USB, would that create an infinite loop of audio?
