Zazi, I reached out to Steinberg US support and just had a call from them. Here’s an update on this issue. Steinberg support replicated this issue (reverbed crunch in fade ins on mixdowns) in their testing, and identified it as a technical bug in Cubase. They will escalate the issue up to the Cubase development folks, who will hopefully fix it in updates. Jeff, the Cubase support representative, told me the issue also presents itself in newer builds and fancier versions of Cubase (Elements 9, Artist, Pro, etc.). So upgrading and updating your Cubase version will not fix the issue. Jeff said he’d get back when they find something that helps. I’ll keep you posted.
