I’ve seen many demos of single Moogerfooger pedals by themselves. They’re great that way, they often allow more extreme effects than a guitar pedal of the same type. However, I have not seen many videos of the interactions you can create between multiple Moogerfooger pedals.
This is a video showing a little bit of the interaction you get when you send audio from the Animoog synthesizer app on the iPad through the MF-101 Lowpass Filter and then into the MF-104Z Analog Delay. The filter module has a envelope output. When you play something louder into the filter, a larger amount of voltage gets sent out of the envelope out. You can use this to control other effects.
