10Who presses go: show control and timecode

The short version: A big electronic dance music show has four or five departments - lighting, video, lasers, special effects, sometimes automation - that all need to hit the same moment. There are two ways to get them there. Lock everyone to timecode, a running clock that travels with the music, so that every cue fires at a fixed position; or have skilled operators play their departments live, calling cues to each other over comms. The documented flagship shows split both ways, and most headline productions appear to mix the two. Whatever the method, the serious ones run a second console, a second server or a second machine that can take over without the audience noticing.

How a timecoded show works

Timecode says where you are in a show - hours, minutes, seconds and frames - and the networks section above explains the formats: SMPTE LTC carries it as an audio signal, and MTC carries it over MIDI¹⁸³¹⁸⁵. In practice, SMPTE timecode is "typically recorded on one audio track" alongside the show audio and decoded by a reader at playback, and Pangolin describes it as common at large festivals and permanent installations²⁸⁴. Pangolin, maker of the BEYOND laser software, sells a dedicated reader for exactly this²⁸⁴.

Every department then follows the same clock. A media server such as disguise can chase external timecode as LTC or MTC through its transport manager, and can also take cue commands by MIDI, MIDI Show Control, OSC or Art-Net and jump to tagged points on its timeline²⁸⁵. A lighting console runs a timecode cue list. A converter box such as Visual Productions' TimeCore can generate, follow, convert and display timecode, and one unit has been used to sync several BEYOND laser computers via Art-Net from a lighting console²⁸⁶. Pyro and flame systems can take cues from the same timeline, behind their own arm and safety channels (see the effects section).

The payoff is precision and repeatability: the strobe hits the snare, the confetti fires on the drop, and it happens the same way every night, even with a different crew on the console. The cost is preparation and rigidity. Building a timecoded show means programming every department against a fixed audio timeline, which makes sessions long, and the whole thing breaks if the track order changes²⁸⁷²⁸⁸.

How a live-operated show works

The alternative is busking: a lighting operator plays the rig live on faders and buttons, a VJ performs the content, and a show director calls the big moments. It adapts to a DJ who changes the set, extends a breakdown or goes back-to-back with someone, but it depends entirely on operator skill²⁸⁷.

There is a middle path for DJ sets with no fixed timeline. Since 2017, CDJs have been able to send real-time waveforms and track data over PRO DJ LINK to ShowKontrol, which can generate SMPTE timecode synced to whatever is playing on the decks and trigger Art-Net, TCNet and MIDI cues¹⁸⁸. In effect, each track carries its own timecoded show, and the DJ can play the tracks in any order. As of October 2026 the newest version of this idea is automatic: SoundSwitch inside rekordbox analyzes a library for phrases and instrumentation and generates a light show per track, which lets the lighting follow the DJ "without a separate lighting operator"¹⁴⁵.

What the documented shows actually did

Trade press production profiles are the best evidence we have, and they do not support the idea that every big electronic dance music show is locked to timecode.

• Illenium, Ascend tour (autumn 2019). Described by PLSN as "a time coded show" for lighting and video, which made the programming sessions long. Lasers were programmed in rehearsal with no timecode mentioned, and the show had live elements: guitar, drum pads and several performance positions²⁸⁸.
• Illenium, Trilogy at Allegiant Stadium (2021). Two full-size grandMA3 consoles, "an active unit and a backup unit"²⁸⁹.
• Eric Prydz, HOLO (2018). TPi reports the show was run live with no pre-sequenced elements, on Avolites Ai media servers²⁹⁰. HOLOSPHERE, the later EPIC show, also ran on two Ai servers, a main and a backup²⁷⁰.
• Swedish House Mafia, Paradise Again (2022). Automation cues were triggered manually by the show director from Resolume, and camera feeds and Notch effects were operated in real time. Timecode is not mentioned in the profile²⁹¹.
• Martin Garrix (2017 onward). At the 2017 launch his lighting designer ran lighting live and called lasers over comms²⁹². The ANIMA show at ADE in 2018 used two grandMA2 consoles plus a smaller grandMA2, run live, with video and cameras live in Resolume and Notch²⁹³.
• Illenium, ODYSSEY at Sphere (March-April 2026). A pre-built 90-minute visual narrative, with stems played and improvised live on motion and touch controllers; the interview does not say how the two were kept in sync²⁹⁴.

We found no source documenting a headline electronic dance music festival show with every department locked to SMPTE timecode. That absence is itself a finding.

Hybrid is the norm (our inference)

Put those profiles together and a pattern appears, which we are labeling as inference because no source states it outright. Headline electronic dance music productions are usually hybrid: timecode or pre-built content for set pieces and for some departments, live operators for the rest. One practical guide gives the typical split as lasers on timecode with washes busked²⁸⁷. The likely reason is the format. A touring band often plays a fixed setlist; a DJ is often booked partly to not do that. A fully timecoded show locks the DJ into a fixed running order, which cuts against that.

The roles follow the method. The profiles name lighting programmers, laser programmers, automation operators and show directors; "playback engineer", a title familiar from pop touring, did not appear in any electronic dance music production profile we found²⁹¹²⁸⁸.

Redundancy: the second everything

A show that depends on one computer is one crash away from darkness, and the documented answer is duplication. Illenium's stadium show ran an active and a backup grandMA3, with the spare actually running the first set²⁸⁹. HOLOSPHERE ran main and backup media servers²⁷⁰. A promoter's guide to timecode adds a checklist that matches common practice: fallback looks that an operator can fire by hand, emergency override cues, isolated timecode paths, redundant audio interfaces and backup timecode generators²⁸⁷. It is a blog rather than a standard, so treat it as a sensible list rather than a rule.

Two lessons follow (ours). First, the backup has to be live, not in a flight case: a tracking backup console that mirrors the main one can take over in seconds, while one that needs booting cannot. Second, the most important fallback is a person. If the timecode drops out mid-set, somebody needs to be able to busk the rest of the show by hand, which is one more reason live operating skill has not gone out of fashion.
