I’m trying to capture tones from my DAW plugins to my Nano Cortex. I followed this tutorial on how to do it and when I captured the tone the final output has no distortion - when I A/B it the captured tone has no distortion and my original tone from my daw going into the capture input sounds good. I know the Nano is getting the tone because I am monitoring with headphones from the nano and I can hear my tone through it from my daw. The capture input is receiving the daw tone. The gain is also in the green and looks good when I am in the capture section. I’m using an Apollo Twin X and the routing should be right according to this video.

I am not sure if there is anything wrong with my device. ---

Ohh I have same problem. However, when I capture Pedal, there is no problem. Can you solve your problem ? ---

To be honest, none of my attempts to adjust plugins have been successful; there’s always a big difference. I think a tutorial from Neural would be helpful, showing us the sweet spot levels to get better results.
