So, I did some digging through the archives, and didn't actually come up with an answer that solved my problem. I'm pretty new to QC, so I apologize if this is a newbie question.

I have a bunch of particle systems, and I want them to operate inside an iterator, instead of having a bunch of copies (16 for now, but ideally, this should be generalized to any number)...I have an iterator, with a macro inside it, and inside that is the actual particle system. It's set to use external time, and the time I feed it is patch time + index. This causes some crazy, yet almost-decipherable flickering when the thing is going. On the other hand, if I unroll the iterator and wire all 16 copies up by hand (copies of the macro *containing* the particle system, mind you!) then everything works beautifully.

Long story short, it does precisely what I *want* it to, but it seems I should be able to do this with an iterator instead of the huge morass of connections I have going on now. I created a version of this thing that allows you to switch back and forth between the two mechanisms, so hopefully someone can point me in the right direction. Just open up the composition: I left notes inside explaining what's going on and how to switch back and forth between the two mechanisms.

Oh, I guess I should mention: it's an iTunes visualizer, so you'll need that going in order to get anything more than a black screen out of it. Get the composition at the following address. I put it online so you wouldn't have to download it via mail if you weren't interested. :)
