Cubase 13 Pro: info about Expression Map and audio output

HI. I have two problems.1: I have Cubase 13 Pro and I have to use an expression map from VSL, Synchron Strings Pro. It’s the first time I’ve used it, and I struggled to understand how to use it because I had only inserted it in the inspector and then I realized I had to put it in the track editor too. Now I can see the articulations but I have a problem. I select the notes that I want to play with the same articulation, and then assign that articulation to them by drawing it with the mouse in the articulations-dynamics controller lane. But then if I realize that that articulation isn’t right, I don’t know how to change it. If I delete the articulation, the notes in the editor are also deleted. What should I do? 2: every time I open Cubase, the audio output does not connect to the PC speakers and I have to connect it every time. What should I do so that it remains connected by default? Thank you very much.
