Version: Cubase 11 Elements on Windows 10
When the “VST Amp Rack” is used, it causes a pop/click noise on the exported WAV or MP3 file. The pop appears whenever the plugin receives a signal for the first time. The pop/click noise disappears when the plugin is deactived or removed from the channel inserts.
Workaround: place a random WAV with a signal at the beginning of the track. The pop/click noise happens when the plugin receives a signal for the first time. Use the locators to mark the area to export after that dummy WAV (see screenshot below).
