I have attempted to utilize both the line In/Line Out and S/Pdif for reamping and am running into the same problem with both. A high-pitched feedback. Any ideas?
If it matters, I just updated to ProTools 12 and just installed a Focusrite Scarlett 6i6 interface just so I could have both options available for reamping.
On ProTools, it shows me inputs for S/pdif as Left and Right (which strikes me as odd when I only see an "in" and "out", but I'm not technically inclined and don't know the finer workings of S/pdif).
