The ability to listen to the delta signal of a plugin to clearly hear what it is ading would be really handy to have.
I believe that Reaper has had this feature for a while. Some plugins have this feature built in, and Wavelab also has it. It would be nice to see it added to Cubase.
Still having issues to get it 100% right because it needs to be gain matched correctly when compensating with plugins. I need to spend more time perfecting it until Steinberg integrates it in the workflow. I am sharing this as a starting point for a solution. the beauty of it is that at the end we will be able to listen to a global Delta / Solo Delta, if we were able to perfect it. Hope this will help.
Setup is simple, Create a cue mix (Delta) with output to '“No bus”, Insert the utility follow the setup as shown in picture.
