The Stage Lights Engine: A Lighting Rig, Not a Readout

Every other engine in the catalog visualises the signal. A bar is a band. A ring is a frame of spectrum. A landscape is a few seconds of history. Stage Lights visualises the room: a lighting rig rather than a readout: beams, haze, pools and chases cued by the beat.

Fixtures have positions on a truss. Beams have a source and a throw. Haze is the thing that makes a beam visible at all. It is the look a live clip has, and none of the other engines produce it.

A lighting desk is cued, not faded

This is the reason Stage Lights is the most beat-native engine in the catalog. A real lighting operator does not slowly ride a fader to follow the mix; they strike a fixture on a beat and let it decay on its own envelope. The engine works the same way.

Every mode drives its fixtures from per-element envelopes triggered by the beat, and the beat count advances which group fires next. That is what produces a chase: light travelling across the truss, rather than every lamp blinking in unison. Turn the chase groups down to one and you get exactly that unison blink, which is a useful thing to hear once so you know what the control is buying you.

Six rigs

• Beam Fan is the default: one rig position at the top of the frame throwing a fan of beams across the stage, each beam swaying slightly on its own phase.
• Laser Sweep fires from alternating sides of the frame. Lasers are thin and long, so they are drawn as strokes rather than cones, each sweeping on its own quantized phase.
• Spot Rig hangs fixtures along a truss, each with a vertical cone that tilts and an elliptical pool on the floor beneath it. It is the mode that most reads as a stage rather than an effect.
• Par Wall drops the beams entirely and gives you a back wall of par cans chasing group by group. Just the lamps, which is a surprisingly strong look behind a logo.
• Strobe Bars pulses horizontal battens in sequence. Note the word bars: these are bounded shapes over a dark stage, never a full-frame flash.
• Follow Spot is a single fixture tracking a target that only moves on the beat, so the spot lands with the music instead of wandering around the frame.

Photosensitivity is a design constraint here, not a disclaimer

An engine whose whole subject is flashing lights had to decide this before it drew anything. There is no full-frame flash in any mode, Strobe Bars included. Beams, pools and bars are bounded shapes over a dark stage, and the brightest term any of them reaches is an alpha on a shape, never a fill of the entire canvas.

The trigger rate is capped too. Fixture envelopes are gated by the beat latch, whose lockout window caps firing at five times a second however the track is analysed. A double-time hi-hat pattern cannot turn the rig into a 20 Hz strobe.

The controls that make or break a rig

• Fixtures is the lamp count. Few and wide reads as an arena; many and tight reads as a wall. Par Wall arranges them into a grid derived from the count, so this control changes the shape of the wall as well as its density.
• Haze is the atmosphere a beam is drawn on, and it is the single most cinematic control in the engine. At zero you have geometric wedges; turn it up and you have air.
• Beam spread is the cone angle. Narrow is a searchlight; wide is a wash.
• Fixture decay is how long a struck lamp takes to fall. Short is percussive and strobe-like. Long is a club with a lot of smoke in it.
• Chase groups is how many interleaved groups the beat cycles through, and therefore how the light travels. This is the control that turns a blinking rig into a moving one.

Colour matters more than usual on this engine, because a lighting rig is mostly colour. The engine's own defaults lean warm against magenta, and the shared Colour mode (duo, gradient or full spectrum) decides whether your fixtures are two colours in alternation or a whole wash across the truss. The Stage Lights engine reference lists every control that is in scope, and its setup effort is rated easy: it looks right almost immediately, which is not true of every engine in the catalog.

What it is for

Anything that wants to feel like a room with people in it. Live-set uploads, DJ mixes, club and festival edits, hard dance, and any release whose artwork already has a stage on it. Par Wall and Spot Rig behind a logo produce a convincing tour visual; Follow Spot works surprisingly well for a single vocal track, because the moving pool gives the frame somewhere to look.

It is the wrong engine when the viewer is meant to read the music rather than feel the venue. For a literal readout, use Spectrum or Bars; for structure that switches on the beat without the theatre, Lattice is the geometric cousin of the same idea.

Open it in the editor, start on Beam Fan, and do only one thing first: push Haze up. Almost every complaint about this engine looking cheap is a rig with no air in it.
