A lighting control surface in close-up: banks of faders, rotary knobs, and backlit buttons.

Composite the show one layer at a time.

A layer runs one effect on one set of fixtures, with an opacity and a blend behavior. The stack combines bottom to top into the single picture your rig plays, so layer order is part of the look.

  • Additive adds this layer's light on top of the stack below
  • Override replaces the stack below, in proportion to opacity

Scheduled in beats.

Each layer plays against a grid of on/off slots, sixteen per bar. Paint a pattern and it repeats every loop, from 1 to 128 bars. The schedule is written in beats, so changing the tempo stretches the whole show and every effect lands on the beat it was written for.
  • Speed multiplier run a layer faster or slower than the master tempo
  • Beat offset slide a layer's phase earlier or later so layers chase each other
  • Hold fade a layer out from the level it was already sitting at

Lo-fi close-up of one timeline layer's beat grid, a layer named Chaser across two bars. Each bar holds sixteen slots, four per beat. Filled slots mark where the effect plays and empty slots where it stays dark, with a ruler counting beats zero to eight above and the bar boundary marked at beat four.

Momentary hits over everything else.

Bumps are layers you fire by hand and hold. They always composite above the running timeline whatever the stack order, so a strobe or a color slam lands over the show for exactly as long as you hold the pad. Map them to a MIDI button or an incoming DMX channel.

Lo-fi mockup of the Bumps panel, a bank of hold-to-play bump buttons named Chase, Decay Flash, Blocks Bump, Lines Bump, Scanner Bump. Each button shows its layer name with a green Bump category dot, an edit control, and a drag handle. The Chase bump is held down, highlighted with an orange selection ring, and a dashed Add bump button ends the bank.

Drive the whole thing from a controller.

Map a MIDI controller to layer opacity, solos, bumps, tempo, color, and fixture parameters. Feedback out drives the pad LEDs and motor faders. Or map incoming DMX and Art-Net so a console already on the truck steers the show. A visual overlay binds controls in place.

Every edit is reversible.

Spectralite keeps a full undo and redo history across your edits, with a history panel to step back through them. Try a look, drop it, and move on.
