I just bought a Presonus Audio box Studio One 4. I like it and find the recording process pretty easy to understand (with the help of the video tutorials). I also have a Line 6 Tone port digital interface that I have used for years. I love the preset guitar/ bass/ vocal sounds on the Tone port. My Question is, how (or can) do I plug my guitar or mic into the tone port but hear it as I record through the Audio box? I can only hear if I switch my headphones into the Tone port, but it has a bad (noisy) headphone input. That's one of the reasons I bought this new interface. I can record from the Tone port, just want to listen through the Audio box.
