A Script CHOP that generates smooth, mean-reverting procedural noise — perfect for organic camera drift, floating objects, generative motion, and anything that needs to feel alive.

Parameters
Motion
Range Min / Range Max [-1, 1] Output bounds. The normalized [-1, 1] motion gets mapped to this range. Default [-1, 1] means output matches the raw sim. Set to [0, 100] and your channels wander between 0 and 100.
Speed 1.0 How fast time passes for the simulation. Speed=1 is real-time. Speed=5 means the OU process evolves 5x faster — more ground covered per frame. Transitions are smoothed so dragging the slider doesn't cause jumps.
Amplitude 1.0 Output multiplier. 0 = silence, 1 = full range. Useful for fading motion in and out.
Reversion 2.0 How strongly the motion pulls back toward the center point (theta in the OU equation). High values = tight orbit around center, snaps back quickly. Low values = lazy wandering, barely cares about center. Zero = pure Brownian motion, no pull at all.
Roughness 0.5 Controls the smoothing filter on the output. 0 = very smooth, flowing motion (spring with ~2s settling). 0.5 = moderate. 1 = raw unfiltered OU, no spring at all. Doesn't affect speed, just the texture of the motion.
Range
Per-Axis Range Off Toggle to set different min/max per axis. When off, all axes share the same Range Min/Max. When on, each axis gets its own bounds — useful when X needs [-180, 180] degrees but Y only needs [-10, 10].
Range Min/Max X, Y, Z [-1, 1] Per-axis output bounds. Only visible when Per-Axis Range is on.
Axes
Affect X / Y / Z All on Per-axis enable toggles. Disabled axes output zero.
Advanced
Center X / Y / Z 0 The point each axis drifts toward, in normalized [-1, 1] space. Default 0 = center of range. Set Center X to 0.5 and tx will hang out in the upper half of your range.
Seed 0 Random seed for reproducibility. 0 = unseeded (different every time). Any other value = deterministic — same seed always produces the same motion after Reset.
Independent On When ON (default), each axis gets its own random noise — tx, ty, tz move independently in 3D. When OFF, all three axes share the same noise value each step, so they move together in lockstep (motion along the diagonal). Useful if you want correlated movement across channels.
Reset Pulse Snap all channels back to their center positions and re-seed the RNG. Fresh start.
