The most common way is to route out a MIDI track with AutoLFO to a virtual port and then back in to the quick controls via virtual port (LoopMIDI etc.). At which point you may as well just be modulated externally or by more capable plugins like MIDIShaper, or those that wrap other VST’s and modulate internally.
So yes, there’s plenty of ways to do that, but they become quite involved and you’re limited to focusing on one track at a time using the quick control route.
You’d also have to make sure the LFO tool stops sending when other tracks are selected or you’d be modulating the wrong quick control parameters.
i.e. the basic setup would be:-
MIDI TRACK > Auto LFO Insert > Virtual Port
Virtual Port > Generic Remote/Quick Control mapping
Would give you something like this:-
And then you’d use that MIDI Track to control the modulating parameters, and write the automation when you’re happy with the results.
The other method would be to create generic remote mappings that hard link to VST parameters in specific mixer slots, trouble with that is that the generic remotes cannot be loaded per project - so very hard to manage.
If you want full step by step instructions and you’re on windows I can happily show you.
It’s insane that the core of Cubase is entirely MIDI CC driven still. There’s no form of VST parameter modulation, and you can’t even draw LFO shapes into the automation lanes.- which would be a basic improvement.
