Because when I recorded both the dry di-signal and the wet signal through s/pdif I had such low output on the dry left signal and the wet stack signal was very high. To add gain to the low dry signal I had to first go and change the volume on the stack and raise the overall volume. And I had to do it over again with the next guitar. To me it would be so cool to be able to easily control both signals within seconds, if there were to separate output gain knobs. To make sure that the wet right signal doesn’t distort and exceed the digital 0 dB I have to adjust the signals and the whole stack.
To make the signal stronger, we would have to include a boost for the SPDIF signal, which we would never do due to clipping reasons.
When the Clean Sense parameter is set right, then the dry signal is leveled correctly.
Why don‘t you boost the signal in your DAW or leave it where it is?
Does this level matter in a recording?
