Hi
I have come to the conclusion, record your instrument at a higher input and as Rodger states " We have been spoiled"!!
It is down to too much input gain which causes that noisefloor on the channel strips.
I must admit Audacity solves the issue by taking a small sample of the noise and then applying it to the whole track. As it is about -50db aprox it does the jobby . Can Cubase 10 do this??
all the best
John
