From Preset to Creation – Custom Programs and Creative Programming for Conventional Stage Lights

Programming Basics for Stage Lighting: Understanding Cues and Timelines

The foundation of all complex light shows is an ordered sequence of Cues. Each Cue is a “full-group snapshot” of stage lights at a precise moment, recording every parameter value (position, color, brightness, gobo, etc.) of every fixture in the venue.

1. Building the Timeline

Like a film director, the lighting designer breaks the performance into consecutive Cues:

• Opening Blackout (Cue 1)

• First Beam at First Musical Bar (Cue 2)

• Color Explosion at Chorus (Cue 3)

This sequence of Cues forms the “musical score” of the light performance.

• Fade Times:

  • Each Cue can have independent Fade In and Fade Out times.

  • Fast Fade In delivers impact, while slow Fade In creates atmospheric, breathing-like transitions.

2. Core Technologies of Creative Programming

Palette Management

• Stores commonly used colors, positions, gobos, and beam angles as global palettes.

• Allows designers to call a palette instead of manually entering values, ensuring consistency and efficiency.

Effect Engine

Powerful console tool for dynamic effects:

• Linear Effects: Lights cycle sequentially in position, color, or brightness, creating wave-like flow.

• Circular Effects: Simulate circular motion of stage lights.

• Random Effects: Generate unpredictable changes for natural atmospheres (e.g., twinkling stars).

Designers can adjust speed, amplitude, phase, and waveform (sine, sawtooth, etc.) for infinite variations.

Grouping and Logic Control

• Group lights by function or position (e.g., all key lights, left beam array).

• Advanced logic functions allow conditional operations (e.g., “when Cue 10 executes, dim all audience lights”), enabling intelligent linkage.

3. Advanced Applications: Timecode Synchronization and Multimedia Integration

For performances requiring perfect alignment with music and video:

• Timecode Synchronization:

  • LTC or MTC files from audio or video sources are sent to the console.

  • The console timeline locks to the timecode, achieving zero-delay, frame-accurate playback.

• MIDI and OSC Triggering:

  • Specific Cues or effects can be triggered in real time via MIDI notes or OSC commands from music software, video servers, or sensors.

  • Enables truly interactive performances.

4. Practical Process of Custom Programming

1. Pre-Design:

   • Pre-programming in visualization software (MA3D) based on scripts or music storyboards.

2. On-Site Programming:

   • Refine programs according to venue, actor movements, and director requirements.

3. Program Optimization and Backup:

   • Optimize Cue order, remove redundancies, and back up program files (console storage, USB, cloud).

4. Performance Execution:

   • Operators make subtle manual overlays or real-time adjustments to adapt to live performance.

5. From Execution to Creation

Custom programming allows stage lights to transcend physical limitations:

• Lights “breathe,” colors “flow,” and shapes “dance.”

• Stage lights shift from passive responses to active visual melodies.

• Mastering light programming transforms technicians into artists, composing emotions with light and shadow, leaving a unique, irreproducible soul imprint on each performance.
