Adding to the mutable/Clouds fiesta -- help with trigger

Anyone have advice for someone just not getting the “trig” parameter in Clouds?

I’ve already been through the manual and several videos, but the parameter still doesn’t seem to, well, do much.

While I understand its designed to “trigger a single grain”, most of the videos describe setting density to 50% and using trigger to “play” cloud as a sampler. Most of the time, no matter what I do with “trig” set to on, nothing happens.

Could someone provide me with a use example?
