Hi. I have a discernible loudness difference if only one track is playing vs mixing tracks.
For example track A is playing and I start mixing track B. as soon as track A is mixed out and stops, the main volume is much lower. Usually Auto gain is enabled and I do make sure the loudness of the tracks is similar before mixing using the meters as guides.
I am not sure what settings I have wrong, but I did notice a difference if I turn FX routing on/off but not enough to solve the problem.
Appreciate your help
