Its very likely not an interference, its just unsmoothed direct control 
of the amplitude. 128 steps are not fine enough...
You can test this, as its more audible on low frequency sine waves. if 
you feed a sound without much overtones/treble and control the volume is 
it more audible? Its hard to believe, that they don't smooth it.
In my Max patches I usually smooth it with 20 ms which creates an 
acceptable latency for volume control...
