I haven't used my Kemper amp for a long time. I thought that I used it in the past with external stereo FXs connected to the direct out and monitor out and going back into the return and alt inputs. Now I can't get it to work. After a lot of fiddling it seems that the SPDIF input is the problem as it is only the left side coming from the DAW. Is this correct? Is there another way that I'm missing?
I think now that it probably wasn't working in the way that I thought, I was probably hearing mono in stereo out as opposed to stereo in stereo out.
