Has anyone ever experienced this annoying phenomena? The thing is, if I copy and paste the audio to a new project, it's totally clean. But as soon as I slab a plug-in on it, it becomes noisy! At first I thought it was the UAD 1176 because that's my main compressor, but the cubase native compressor does the same thing. EQ seems fine. This has happened to both DI'ed and miked signal. My project has under 40 tracks. I'm running a quad-core 8g Rokbox PS Orpheus Cubase 5....What's going on?
