Controlling vst synths from scaler 2 within cubase

I have cubase 10.5 pro and want to control my vst synths from within scaler 2 instead of using the internal synth sounds (switching the internal sounds off)
Can anyone show me how this is done ? There dont seem to be any help/tutorials geared towards cubase its all ableton or fl studio !

Geared toward CB9, but should help:

Glad I could help. It’s always nice when things work out.
