Even a hypothetical app might not be so badly written as to cause noise to appear on the outputs of upstream applications. And would 1/16 rate CV solve this if it did?
Look... *takes a step backwards*....
I'm not expecting a *normal* app to expose its volume control as a CV input at all. Maybe some in this thread are.
I'm reading "CV input" as "invitation to modulate" and, yes, sometimes it makes no sense to modulate at the full audio rate, but sometimes it does. I'm just not sure a special and predetermined 1/16th or whatever control rate is worth the effort (and might even be a performance hit in some cases) for the reasons I described when I entered this thread.
