3 Modules #3: Rings, Peaks, Brain Seed

"Wanted to go with a simple and pretty one to follow up the messy episode 2. This is one of my favourite patches.
Peaks ch. 2 produces a simple, skewed ramp wave LFO which feeds into the Brain Seed seed input. Brain Seed treats this kind of like a sample and hold signal input, and samples the ramp wave to produce V/oct CV for Rings.
However, unlike a regular sample and hold module, Brain Seed doesn't react to a trigger signal. Instead it stores the 8 most recently sampled values, and moves between them as directed by the Cycle CV input. In this case, I'm using a smoothed random LFO from Peaks ch. 1 to modulate this movement. Since it's a random signal, the sampled values are output in random order. But since it's smoothed, it "strums" through adjacent values to get from one point of the sequence to another.
By switching on and off "ReSeed" on the Brain Seed, I can choose to lock down the 8 sampled values (ReSeed off - cycle LED flashes green) which leads to somewhat repeating patterns, or allow new values to be sampled (ReSeed on - cycle flashes red). I'm using this to create movements and repetitions as I see fit."
