Where to find answers

Just started watching the tutorials and finally got to the one I want to focus on-- using Halion Sonic SE, so I opened Cubase and the tutorial so I could stop the video and actually do what it says, one step at a time. Got as far as opening HSSE. The video says to click the preset window and two boxes open: a library of categories of sounds opens on the left, and connected to it on the right is the listing of sounds available in each category.

I do not have a natural intuitive ability with software, so I’m very dependent upon it performing the way the instruction say it will.
