My plugin wants to receive keystrokes from the computer keyboard when it has focus, such as up-arrow, down-arrow, and control-Z. That worked fine in VST2. I’m running the VST3 plugin in Cubase 11 and the keystrokes are not getting sent to the plugin: instead, they are getting processed by Cubase.
Is there something I need to do in Cubase 11 on the plugin track to cause the keystrokes to get relayed to the plugin? Or is there some VST3 interface I need to implement in the plugin software? Upgrading to VSTGUI v4.x is not an option.
