Programming Moving Heads with Light Consoles

Why Programming Matters in Modern Stage Lighting

Programming moving head lights on a light console is more than assigning channels — it’s translating creative intent into repeatable, reliable stage action. Well-structured programming saves rehearsal time, ensures cue-to-cue consistency, and enables complex effects (pixel-mapped chases, music-synced looks, or tightly timed cinematic cues). This guide covers the practical workflow, best practices, common pitfalls, and advanced techniques used by touring LDs, house technicians, and rental houses working with moving head lights.

Understanding moving head lights: anatomy and DMX mapping

To program moving head lights effectively you must understand what each fixture component does and how it maps to control channels. Typical moving head lights include pan/tilt motors, color mixing (CMY or color wheel), gobo wheels, iris, zoom/focus, shutters, prisms, frost, and intensity. Manufacturers expose these parameters via DMX channels (or via network protocols such as Art-Net/sACN).

Key practical points:

• Channel mode: fixtures often have multiple DMX modes (e.g., 8, 16, 20, 32-channel); higher-resolution modes give finer control (16/32-bit pan/tilt, separate CMY channels), but require more console channels.
• Coarse vs fine channels: many fixtures use paired channels (coarse + fine) to increase resolution. Check fixture personality for 16/32-bit pan/tilt configuration.
• Fixture library: always use or import a validated fixture profile on your console. If none exists, create or test a custom personality and document the channel map.

Patching moving head lights on light consoles

Patching assigns each physical fixture to a logical address on the console. Good patch discipline reduces errors in cueing and troubleshooting.

1. Inventory: list model, DMX mode, required channels per fixture.
2. Addressing strategy: group fixtures logically (e.g., front truss 1–12, wash 13–24). Use consistent universes for similar fixture groups.
3. Patch and test: after patching, verify pan/tilt, color, gobo, and macros for each fixture.

Networking and protocols for moving head lights

Modern rigs use DMX512 over copper or network protocols (Art-Net, sACN/Streaming ACN) for large channel counts. RDM (Remote Device Management) allows discovery and bidirectional comms for addressing, firmware updates, and status monitoring. Understanding the tradeoffs helps choose the right approach.

Manufacturer documentation and community forums are good references when choosing a console — check fixture support lists for your specific moving head lights.

Programming workflows for moving head lights on light consoles

A consistent workflow increases speed and reliability. Below is a step-by-step workflow used by experienced programmers.

1. Pre-production: gather floorplan, rig plot, fixture specifications (DMX modes, power, weight). Create an addressing plan and universes.
2. Patch and verify: patch fixtures in the console, verify each fixture responds to pan/tilt, color, gobo, and intensity. Label physical cables and channels.
3. Create palettes: build color palettes (RGB/CMY looks), position palettes (home positions, sightlines), and beam palettes (zoom/iris settings). Palettes speed programming and ensure consistency.
4. Program cues: build cues using palettes and record them into sequential playback. Use careful timing for fades and hold times. Keep cue labels descriptive.
5. Use tracking: tracking allows new cues to inherit attributes from previous cues. This reduces memory usage and makes changes faster.
6. Add FX and chases: use console FX engines or pixel mappers for moving sequences. Parameterize FX using global controls (rate, size, direction) to enable live control.
7. Test and refine: run full cue lists in rehearsal, refine blend times and look transitions. Validate under performance conditions (full stage haze, show brightness).
8. Backups and showfile management: save incremental showfiles and export fixture personalities for redundancy.

Sample quick cue setup (practical example)

To create a simple crossfade spotlight sequence across 8 moving head lights:

1. Patch 8 fixtures and label F1–F8.
2. Create a position palette for left, center, right (store positions per fixture).
3. Create a color palette (cool white, warm white, blue).
   
4. Record cue 1: All fixtures at left position, cool white, intensity 100%, fade 1s.
5. Record cue 2: Fixtures move to center, warm white, fade 2s. Ensure tracking for color if you want color to change automatically.
6. Add an FX to cue stack: a slow pan sweep to maintain motion between cues using the console’s FX engine.

Advanced techniques: pixel mapping, timecode, and RDM

Advanced shows often combine moving head lights with LED pixel content and time-synced events.

• Pixel mapping: Many moving-head fixtures include pixel-mappable LEDs (e.g., LED rings or arrays). Use a console with pixel mapping to map each LED to a pixel universe. For multichannel fixtures, test mapping in a small group before scaling.
• Timecode (MTC / LTC): For music-driven shows, synchronize console cues to SMPTE LTC or MTC. Test start/stop behaviors and ensure console cue lists respond correctly to timecode jumps.
• RDM: Use RDM to remotely address fixtures, monitor lamp hours or temperature, and push firmware updates where supported. RDM simplifies large rig setup and preventative maintenance.

Troubleshooting moving head lights: common issues and fixes

Common problems and practical fixes:

• Jittery pan/tilt — check DMX refresh rate, ensure correct resolution channels are used (avoiding coarse/fine mismatches), and verify mechanical calibration.
• Flicker or strobing — verify LED dimming curve and console PWM frequency settings; some fixtures have selectable dimming modes to reduce strobing on video.
• Dead fixtures — test cable continuity, check terminators on DMX lines, verify correct universe and address, and try direct patching (bypass network node) to isolate the problem.
• Network issues (Art-Net/sACN) — segment lighting traffic onto a dedicated VLAN, use managed switches with IGMP snooping for sACN multicast, and avoid using wireless for critical control traffic.

How to optimize programming speed for live events with moving head lights

Speed is often as important as quality on live events. Techniques to speed programming:

• Use palettes and tracking extensively to reduce repetition.
• Build and reuse macros (sequence of actions) for repetitive tasks like blackout or full-intensity looks.
• Leverage fixture groups and submasters (executors) to keep frequently used looks immediately accessible.
• Create a template showfile for recurring venues with common fixture layouts and default palettes.

Frequently Asked Questions (FAQ)

1. What is the best DMX mode to use for moving head lights?

Use the highest resolution mode you need for smooth movement and fine control (e.g., 16/32-bit pan/tilt for slow, precise camera follow). For shows with extremely large channel counts where console resources are limited, use a reduced mode that keeps essential parameters accessible. Always test both in rig context before the show.

2. How do I avoid strobing and flicker on camera with LED moving heads?

Check fixture PWM/dimming frequency settings and choose high-frequency settings if available. Also use consoles with adjustable dimming curves and ensure frame rate compatibility with camera shutter speeds. Haze/fog levels can affect perceived flicker — test camera under final lighting conditions.

3. Can I control moving head lights over Ethernet, and which protocol is better: Art-Net or sACN?

Yes. Both Art-Net and sACN are common. Art-Net is broadly supported and simple to use; sACN (E1.31) is designed for scalable professional systems with multicast and better network segmentation options. For large distributed rigs, sACN on a properly configured network (VLANs, IGMP) is usually more robust.

4. What is the fastest way to program a typical concert rig with 48 moving head lights?

Use a template showfile with patched fixtures, pre-built color/position palettes, and a default FX bank. Group fixtures logically, use tracking for cue inheritance, and place common looks on executors. Reuse macros for repetitive scene changes to reduce manual programming time.

5. How can I remotely diagnose moving head issues during a show?

If fixtures and consoles support RDM, use RDM to query lamp hours, temperature, and address information. For networked fixtures, use manufacturer network tools to verify packet flow. Always carry a spare fixture and patch test cables on-site to swap quickly.

6. Should I use coarse/fine channels or 16/32-bit resolution for pan/tilt?

For camera-follow or precision work use 16/32-bit resolution to avoid stepping in slow movement. For fast-moving concert looks where extreme precision isn’t visible, coarse channels are acceptable and reduce overall channel consumption.
