I want to be able to automate 3 knobs on FM8 with 1 automation/knob. kind of like what ableton does with the macro controls. Is there any way to do it in cubase?
no.
(see my post here if you want to jump through hoops; i tried and reckoned it is not worth it and it’s more convenient to oursource these sounddesign tasks from ableton live: Steinberg Forums )
