I’ve setup the filename scheme as follows :
The result is
I expect that the filename should like CD B - 1 - TRACKNAME
What is the source that you try to render?
The source is an audiomontage or what did you mean?
If this is an Audio Montage, the CD Group has no meaning. The CD group only has a meaning if you a render a CD group or a CD Track that belongs to a CD group.
This being said, I have found a case where what I say above does not happen. This will be fixed in 10.0.10.
