According to page 599 of the Cubase 9 Operation Manual, “Any VST 3 plug-in features multi-channel support and can therefore be used in a surround configuration, even if it was not specifically designed for surround.”
But when I insert a stereo VST3 plugin into a 5.1 surround track, for example, it only affects the L/R channels. If I want to affect the other four channels - C/LFE, Ls/Rs - I must insert two more copies of the same plugin and route the audio using the Channel Settings > Inserts > Routing panel. I’m guessing this isn’t what they meant in the manual. Instead, it sounds like just one instance of the VST 3 plugin should do the trick.
So, is there some other method of inserting a stereo VST 3 plugin so that it affects all six channels of a track?
Any assistance is appreciated.
