I am able to load GPO as a plugin on an audio channel but am unable to see it as an option on a midi track output. All other audio instruments that I have installed appear in the midi output dropdown menu but not GPO.
The only thing that is in that menu is in a sub-menu (output/pre-defined/GPO studio) But selecting any of these does not seem to do anything.
To top it all off, I have just re-installed GPO and upon entering Pro-Tools I find that there are absolutely NO plugins apart from GPO. Needless to say, GPO does still not appear in the Midi channels output list.
