This may be an unpopular opinion, but modelers used as interfaces are a bad idea. They are almost always under featured and from what I’ve seen, plagued with problems while doing interface duty.
I’d get myself at least a cheap Behringer or something so I can get stereo effects into my computer. A pedalboard is a completely different thing, most are in mono anyway. It would be a shame not to hear these fx in stereo in a good listening environment though. FWIW my H9 is wired stereo to my FM9 for my live rig and it MATTERS.
