Estoy intentano conectar una controladora Faderport 8 y, efectivamente, el programa la ha reconocido como 'Superficie de control' pero no actua (no está instalada en realidad).
One possibility is that in Audition's preferences, you may have to edit the control surface. So try Edit>Preferences>Control Surface and select your Faderport, which should show in the list. If it doesn't, then add it, as you've shown - also you might want to put a check in the MTC box. Then when it's installed, select it and click on 'Edit'. You should now be able to see the way the controls are assigned, and alter the functions of some of them if you want to.
