Laser Chase

Sweeps a brightness window across your lasers in sequence, so one (or a few) light up at a time while the rest go dark. The classic chase effect for multi-laser shows: spotlights that move, bounce, or jump between projectors.

Inputs

Port	Type	Default	Range	Description
Frame	Frame	—	—	The frame to apply the chase to
Phase	Scalar	0.0	0–1	Position of the brightness window in the sequence
Width	Scalar	1.0	0–16	How many lasers are lit at once
Fade	Scalar	0.0	0–1	Softness of the brightness falloff at the window edges

Outputs

Port	Type	Description
Frame	Frame	Input frame with chase brightness applied
Brightness	Scalar	Current chase brightness for this laser (0–1)

Controls

Direction: Forward, Reverse, Bounce, or Random.
BPM Sync: Lock the chase phase to the global BPM clock.
Sync Rate: Beat division when BPM Sync is on.

Ideas

Animate Phase with a Phasor for a smooth sequential reveal across your laser setup.
Use Bounce direction for back-and-forth sweeps that ping-pong between the first and last laser.
Combine Width and Fade for smooth spotlight transitions; a narrow width with high fade creates a soft traveling glow.

Tips

The Brightness output is useful for secondary effects. Wire it into color or scale to make lasers respond beyond just brightness.
Phase, Width, and Fade are sampled once per frame (not per point).
With a single laser, the chase has no visible effect. It's designed for multi-laser output groups.

Effects: add Chase to an output group without editing a clip graph
Laser Index: raw laser identity for custom per-laser logic
Phasor: drive the chase Phase input with a steady ramp
Output: final transform applied after chase brightness
