Unable to control VST3-Plugin in real time

Hi all,
Have installed Plugin Alliance SPL Twintube. Have the switch for real-time control on, but the plugin configuration remains greyed out during playback. Is there a way I can switch to the plugin controls?
Thanks
Richard

Hello @richardl3,

Can you send me a copy of the “Debug Info”? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message
