That helped a lot!
Now I’m looking for Bear in the Forest sounds to try to get into the custom soundset. It would be awesome if I could get some bear one-shots, and some kobold one-shots, and some trap one-shots, all in the same mood, with only the slider tracks I’m going to use, instead of hunting through tons of useless-to-me slider bars. Is there a way to reorder those, please? I’ll bet there is.
Also, can I post a screen-shot here in the forums, showing what my setup looks like? That would probably help explain what I don’t have the vocabulary to explain yet.
Anyway, here’s what I’m trying to accomplish for a rainy night encounter. (SS is SyrinScape):
SS: Custom Mood > Cedar Creek Rivers.
The camp you’ve chosen holds—barely.
The ground is soft, but not treacherous. The trees thin just enough to give you a sense of space.
SS: River gain 20%, Waterfall gain 10%.
The river nearby is loud tonight.
Not violent—but constant. A rushing, endless presence that fills the air and swallows smaller sounds.
SS: River Fade 20%, Waterfall Fade Back 20%
Your fire struggles. Smokes. Refuses to take.
There is a smell now. Not the forest.
Something warmer. Heavier. Animal.
SS: Add tense background music
Revealing the Peckish Bear
*Encounter: 03a Black Bear
First Movement
At the edge of the firelight— something shifts.
SS: Bear snuffle.
Large.
Slow.
**SS: Add low foliage movement / heavy rustle (very low) - tense music intensifies, some faint drumbeats in the music maybe **
A shape resolves in the dim light.
Broad. Low to the ground. Wet fur clings in dark strands.
It does not look at you. Not at first.
It sniffs.
DM, whispering: I want to remind you that in situations like these, any verbalizing or making sounds with your mouths has to be performed in-character. So you can try to whisper softly to someone nearby, if you wish, but no group chatter until the airwaves aren’t so key to the scene. 
Behavior Beat (No Initiative)
The bear moves with slow, deliberate purpose:
Toward packs
SS: Rustling Noises, some inquisitive snuffling
Toward food
Toward scent
It is not stalking.
It is not charging.
It is… searching.
SS: Add soft snort / breath (low, intermittent)
DM Note (internal)
*No initiative yet
*Let players react
*Let tension build
*This is not combat—yet
SS: Violence Triggered! drop into tense escalation potential bear-fight until they deal with the situation.
Also, I’ll add in the snickering giggles of the kobolds who lured the bear here as a distraction, and are now plundering and trapping the camp’s bedrolls, boots, etc. And, if they have long enough, they’re affixing ziplines to things they want to snatch, running off into the woods so that when the camp goes bananas after the bear, they can steal even more of the party’s gear. And hopefully lure the party out into even more traps.
Anyway, I think you can see what I’m looking for from SS. I’ve got the first mood set. Now I’m looking for a SoundSet with some good snuffly bear sounds, and then tense wilderness combat in the drizzling soggy temperate rainforest in late February. (Unless there’s a way to build my own soundset with its own sound tracks instead of jumping constantly to the source soundset. So clunky. 
Any pointers, for any who slogged through all of that with me? whew
TY! This is turning out great, if I can figure out how to use your product.
