Cello Moods Articulation/Swell Speed

I'm just trying out Cello Moods and liking what I'm hearing, but I'm having trouble getting it to play expressively from note to note. I heard it drop naturally from one note to a lower one but it's since stopped doing that. Do notes have to last x seconds in order to hit a cycle or something? And is there a way to modify how quickly a note swells? It sounds like the sample they created has some shorter swells than I can get on my own. I have some shorter notes that need a faster swell in order to move along, but it's just dropping down to minimum and taking a while, so it sounds like it just stops playing between notes.

My project is in 6/8 at DAW 74bpm (if you know, you know), and I'm trying to do some duplets at one point when it's giving me the silent treatment. I don't think it's all that fast. Am I trying to push it too fast?
