Coming back to this issue as the OP. I’ve been testing quite a bit on Studio One 3, and not getting these issues at all. From the feedback of users who have tested it, it seems to be that its an issue for all Cubase users, but most of the time nobody notices because it is such low level and in most cases inaudible.
So …
- Why would this happen in Cubase, but not another DAW with same settings/plugins?
- Is it necessarily a bad thing, if the levels if these artifaccts are so low - can it actually affect the quality of final output when mastered?
