Solo Indication (play out)

Which do you want: “volume”-only or “soloistic,” with all of the other aspects that entails? (This is an either/or choice.)

At the moment, having a simple, free VST library, I just want to turn up the volume, because I can’t do anything else, as I’ve already been told here.

— This is in case someday I will have VST libraries that can do this

Well, what if I don’t have Dorico + NotePerformer, but Dorico + so let’s say Iconica Sketch (or HALion). In this case, which MIDI events change when manually dragging these control points?

For the sake of playback:
Using mixing methode:
You could get some more precense of one or more sounds by using abit ambience to the backing sounds and a plugin for “precence” to the solo sound. It will move the soloist sound forward on stage.
