Using Auto-Correlate as Unintended?

[Duckett]

Was wanting some thoughts; I've had some interesting results with feeding, say, two separate LFO signals into the Auto-Correlate module, but would like to know if a tiny amount of noise is needed to keep it "alive" (in other words, would zero values be possibly causing NaN error propagation)? It's entirely possible I'm not even asking the right question- but ye be well-known as patient and wise souls, ye who still be weathering the spam to help amateurs like me

Sorry, I don’t know what the Auto-Correlate module is.
Could you post a schematic please?
