Rocket Show SPARK · For theatre, live events & venues

Sound, lights, video & MIDI —
one GO runs the whole show.

A six-week run or a one-night gala: plot the show once, then fire it cue by cue from the GO button, a footswitch or a tablet. Frame-perfect every night — with no laptop in the wings.

Why SPARK

Built for shows that go up tonight.

One box that does one job — so the wings stay quiet and you can watch the stage instead of a progress bar.

No laptop in the wings

No operating-system update mid-scene, no fan noise in a quiet moment, no crash at the worst possible time. SPARK is dedicated hardware built to play the show and nothing else.

Night forty = opening night

Tracks, click, lighting and video fire together, down to the frame. The hundredth performance lands exactly like the first one did.

Anyone on the desk can run it

One button per cue, in running order. When your regular operator is away, the stand-in still gets the show right.

Product video

Watch SPARK run a whole show.

Two minutes: lights, video, audio and MIDI firing together from a single unit — with no laptop anywhere in the rig.

Nothing loads from YouTube until you press play.

How it works

Three steps from cue sheet to curtain.

01

Plot the show

Build every cue on your computer, tablet or phone: backing tracks and click, video, lighting scenes, MIDI, and timed triggers for anything else on stage.

02

Set the running order

Group your cues into a set, in show order. Cues that follow straight on chain automatically; the rest wait for your GO.

03

Call it

Fire cues from a wired GO button, a MIDI footswitch or drum pad, or a phone or tablet on the venue network. No computer at the venue.

Cues & triggers

One cue. Everything at once.

Every cue is a single file. What starts it, and what it fires, are entirely up to you.

What fires a cue

Wired GO button
Two digital inputs take a simple contact closure — a stage manager's GO button, a footswitch, or a relay from another system. Terminal blocks are in the box.
MIDI
A note or program change from the MD's foot controller, a pad, or the pit's keyboard rig starts the next cue.
Phone or tablet
The web interface runs in any browser on the venue's Wi-Fi or Ethernet — no app to install on the crew's phones.
Another SPARK
Chain units over LAN or MIDI so one unit triggers the rest of the rig.
By itself
Autoplay chains the next cue in the set the moment the current one ends — for sequences that must run without a hand on the button.

What one cue fires

Sound & click
Two independent stereo outputs: the house mix on one, a click for the MD or a foldback feed to the pit on the other. Usable as four separate mono outs.
Lighting
A full lighting state over DMX512 or Art-Net — driving the fixtures, dimmers and moving heads you already have.
Video
HDMI up to 4K to a projector, screen or LED wall, locked to the audio.
Your MIDI rig
Program changes and control messages at exact timestamps — patch changes on the keys rig, presets on the guitar amp, on the beat rather than from memory.
Effects & practicals
Four digital outputs switch at defined moments inside the cue: haze, confetti, a practical — anything a relay can handle.

Cues are reusable across sets, so the full evening show, the matinée and a cut-down schools version can all draw on the same files.

The hardware

Built to disappear into the rig.

Professional connectivity in a compact, road-ready unit — rack it, tape it down, and forget it's there.

Drops straight into your stage setup

House mix to the PA, click or foldback to the pit, DMX or Art-Net to the lighting rig, HDMI up to 4K to the projector or LED wall, and MIDI in and out for everything else on stage. Chain multiple units over LAN or MIDI so one triggers the rest.

  • House mix and pit foldback on separate outputs
  • DMX & Art-Net lighting output
  • HDMI up to 4K for projection
  • MIDI in / out & wired GO input

Technical features

Everything a stage needs, on one box.

Sound & click

WAV, MP3 and many more formats. Two independent stereo outs keep a click or cue feed out of the house mix.

Lighting cues

Design states and effects in the open-source designer and run them over DMX or Art-Net.

Video & projection

Up to 4K over HDMI, frame-locked to the music — surtitles, backdrops, playback for a scene.

MIDI to your rig

Notes, program changes and control messages at exact timestamps inside the cue.

GO from anywhere

Wired button, MIDI footswitch or drum pad, phone or tablet — whatever suits the person calling the show.

Sets & running order

Group cues into sets, reorder them for the night, and reuse the same cue in as many sets as you like.

Shows that just run — night after night.

“We've had several light and music installations running on Rocket Show SPARK for over 5 years — among them the famous Zauberwald in Lenzerheide.”
R. Wilhelm Head Smashed
“Setup was faster than I expected, and the support is outstanding. Worth every euro.”
Chris Bluemoon Virus of the Cactus
“Our backing tracks used to run off a drum pad. Today one button press starts the whole set: click, samples and lights, perfectly together every night. And no risk of a laptop overheating!”

Before you buy

The questions we get most.

Can I feed the house and a separate click to the pit?
Yes. SPARK has two independent stereo outputs — four channels in total, also usable as separate mono outs. The house mix goes out on one pair; a click for the MD, a foldback feed or a dressing-room relay on the other, with no bleed between them.
How do I fire cues during the show?
Four ways, and you can mix them: a wired button on one of the two digital inputs, a MIDI note or program change from a footswitch or drum pad, the web interface on a phone or tablet, or another SPARK over the network. The terminal blocks for the wired inputs come in the box.
Can it send program changes to the pit's keyboard rig?
Yes. MIDI Out sends notes, program changes and control messages at exact timestamps inside a cue, so patch changes on the pit's keyboard rig land on the beat instead of on someone's memory.
What if the running order changes?
Cues are individual compositions, grouped into sets. Reorder a set in seconds, and reuse the same cue in as many sets as you like — full evening show, matinée, cut-down schools version.
Does it replace my lighting desk?
On smaller stages it often does: SPARK outputs DMX512 and Art-Net directly, so it can run the rig on its own. On bigger shows it usually works alongside a desk instead — SPARK handles tracks, click, video and MIDI while the desk keeps the lights. Worth knowing: SPARK sends DMX, it does not take DMX in. If the desk should stay in charge, trigger SPARK from it over MIDI.
Does SPARK work with my existing lighting rig?
Yes. SPARK speaks standard DMX512 over its 3-pin output, so it drives the fixtures, dimmers and moving heads you already own — no need to replace anything.
Is Art-Net supported?
Yes. Art-Net runs over the Ethernet port, so you can drive Art-Net nodes and larger rigs across your network alongside — or instead of — the physical DMX output.
What happens if a unit fails mid-show?
SPARK is built to run unattended for years, but no single piece of hardware is immune. For shows that genuinely cannot stop — theatre runs, permanent installations, ticketed events — we recommend keeping a second unit on the shelf as a backup. Your show files copy across in minutes.
Can I run several units together?
Yes — units connected over Ethernet or MIDI can trigger and control each other, so one unit can drive a whole rig of them. Note that networked units exchange control instructions rather than a shared playback clock: for outputs that must stay frame-accurate to each other, keep them on the same unit.
How long does shipping take, and what does it cost?
Delivery takes roughly two weeks. Shipping is a €40 flat rate worldwide, and less within the EU.
Are VAT, customs and duties included?
VAT is already included in the €795 price. Any customs duties or import charges in your country are paid by you on delivery, as is normal for international orders.
What if it isn't right for me?
Send it back within 30 days, no questions asked. Open the box and try it properly — we just need everything that came in it returned.
