The faders in the VST Connect Plugin set monitoring for the Performer, what he or she hears. Nothing will change on your end when you mess with these, but the Performer side may lack signals if you just poke around. The idea is that the Performer can be hands-free, you determine what he or she hears by adjusting these and the cue mix.
The pots above those faders (RECORDING) determine the stereo mix of those channels sent by the Performer, that is, what you hear and record in the stereo mix. Also individual record enables can be engaged there for recording on the Performer side (up to 16) with the PRO version and later retreived in fill resolution.
