Ok great, got it.
So when you click the snare, do you see the snare remain bright while the rest of the kit is dimmed, as on the image in step 2 in the book?
If you click it again a few times, does it end up sounding or not at all?
Oh I understand now!
Ok so then make sure you continue holding down Control + Shift while you release the mouse click, and only let go of the keys after you've released the mouse click?
I haven't watched the videos, but I'm talking about using Flex Time, slicing mode, fill gaps turned off. The Q depends on the drum groove, how far off it is, and how tight you want it. You could start with only the kick and see where you get.
You are looking at the wrong plug-in, see the name of your plug-in window at the very top (Small room....etc.).
Close it and double-click the correct Channel EQ plug-in.
I'm not sure what you mean? You mean you expect the Drum Kit Designer plug-in to show that the snare is being hit? If that's what you meant then no, Drum Kit Designer does not do that. However you can click the Snare in order to trigger its sound.
