I followed the same process - to click on the name of the VST within the VST Rack (so clicking on the name of HALin5nc5E) for example. Then a menu comes up to select a different VST, and at the top of that menu there is a selection for No VST. When I do that the HALin5nc5E) does go away. However, the VST square (and number) remains, and in its place are the words “No VST Instrument”.
Is there a way to get rid of the VST square? (and the number within the rack it occupies?
