LED Event Manager is a tool for designing LED installations for events. Lay out screens in 2D and 3D, build pixel maps, route signal and power, draw the connection diagram — then export the full set of documents or send a live image over NDI.
Design LED screens for concerts.
A pixel map in a graphics program, a pack list in a spreadsheet, a diagram in a separate drawing, calculations in a calculator — every screen change means edits in several places at once. Here everything comes from one project.
Change a screen — the cabinet count, power and pack list are up to date instantly.
This is not just one wall on a stage. In the app you open tours, conferences, XR studios and trade-fair booths with ceilings, floors and angled screens. The cabinets, signal outputs and power on the cards come from the app's Dashboard, and screens are counted physically (a screen cut across several outputs is one screen). You can open every project in the modules below.
Main wall 24 × 8 m in an arc, cut across two outputs. Two IMAG screens, side hangs, an LED cube above the stage and a ramp made of floor tiles. Output backups on the processor's free outputs.
Eight 50 Hz outputs with backups: MAIN walls cut across outputs, a cube made of walls and a ceiling, a center screen and transparent screens on a separate output. A project by the app's author.
A 10 × 5 m wall in a 40° arc, two vertical IMAG screens and the DJ booth front on two 60 Hz outputs. Screens hung in 3D at different heights.
A 22.5 × 3 m panorama (P1.9) in an arc across three outputs, a speaker's lectern, confidence screens for presenters, portals beside the stage and four totems in the foyer.
A curved 18 × 4 m backdrop (147° angle), two angled wings, a ceiling and a floor. Everything runs at 60 Hz, and the floor tiles draw more power than the backdrop panels.
A 12 × 12 m island booth: a back wall, two angled side walls, a pitched “roof” of four screens, an LED floor, a four-sided tower, a counter, kiosks and a vertical banner.
A booth open on every side: a back wall laid out as a wave, a V-shaped ceiling, a cross-shaped floor, angled interactive tables, four pillars and a convex counter.
Six projects are examples: the layouts and numbers were made up for this presentation. “Nova Reveal” is a layout from the app author's real project, shown under a made-up name.
These are frames from the app's real 3D view. Drag to see the stage from every side, or pick another project. In the app you rotate it the same way, and you position screens in space to the millimeter.
In the app you rotate the view by dragging the mouse, around the center of the model or the selected screen.
Every stage of the work has its own module, and they all read the same data. Pick a demo project and switch views to see the real interface on different projects: from a concert tour to a booth with a ceiling and an LED floor. All screenshots come from the app.

Lay out screens on the virtual stage the way they stand on site — then switch to 3D and check how they look from every side.
Enlarge
Every processor output is a separate canvas with its own resolution. Assign screens to it and you have a ready pixel map — with everything the crew needs on site.
Enlarge
Select an output and draw a line along the cabinets — the app keeps counting how many pixels each processor port carries.
Enlarge
You pick a screen and draw circuits along the cabinets, and the watts add up on their own. Power is counted on whole screens, as they stand in Stage View, so splitting across outputs never gets in the way.
Enlarge
Draw the signal chain from source to screen: media server, mixer, processors, switches, cameras and LED screens. Instead of a separate drawing you get a diagram that feeds the pack list.
Enlarge
The equipment list builds itself from the diagram, screens and signal flows. You only add the small items.
Enlarge
One page with the numbers of the whole event: how many maps, cabinets, signal outputs and kilowatts. Press ⌘D and it's right in front of you.
A selected screen gets a handle in the 3D view: three axis arrows, a square for sliding along the floor and an orange ring for rotation. A plain click moves nothing — you move only what you grab, and the position rounds to 10 mm. You can enter the same values in the screen panel.
Enlarge
The inset shows a close-up of the handle: X (red), Y (green) and Z (blue) arrows, the square on the floor and the rotation ring. The panel on the right shows position and rotation.
Each arrow moves the screen along its own axis only. The green one changes the hanging height while the floor position stays. The bar at the bottom of the view shows the value in millimeters and the difference from the start.
Moves the screen across the floor plane, keeping its height. Dragging the screen itself does the same; when you look at the stage almost horizontally, the screen slides along the wall facing you.
Rotates the screen around the vertical axis (yaw). With the Shift key rotation jumps in 15° steps, without it rotation goes in 1° steps. The ⟲ and ⟳ buttons in the panel make 90° and 15° steps.
X, Y, Z position in millimeters plus pitch, yaw and roll in degrees. You drag the handle or type a value — both ways change the same thing. The Reset button returns to the 2D layout.
Dragging the background rotates the stage around the center of the model or the selected screen, the right button pans the view, and the wheel zooms toward the point under the cursor.
Enlarge
Every cabinet is flat, and the screen bends only at the joints between columns. You set one angle for the whole screen, separate ones for the left and right halves (that makes an S-bend) or one for each joint (up to ±15°), so you get a stage arc, a wave or a convex counter, all the way to the 147° backdrop in the XR studio. The processor still gets an ordinary, flat map.
At trade fairs, screens hang overhead, lie underfoot and stand at unusual angles. Every screen has a position in millimeters and a rotation on three axes, and its pixel map for the processor always stays flat and rectangular.
Enlarge
A back wall and two angled side walls, a “roof” of four screens tilted over the vehicle, an LED floor beneath it, a tower visible from four sides, a counter, kiosks and a vertical banner.
Enlarge
A back wall laid out as a wave from joint angles, a V-shaped ceiling, a cross-shaped floor, angled interactive tables, four pillars, two vertical banners and a convex counter. The same project in 2D is four independent pixel maps.
You hang a screen over the stage and tilt it to any angle. In MotoExpo four screens make a roof over the vehicle.
Tiles lie flat and have their own power per cabinet. The floor counts in circuits and in the pack list like any other screen.
Pitch, yaw and roll set the screen at an angle. Roll 90° turns a horizontal screen into a vertical banner.
However a screen hangs in space, the map for the processor stays flat. A change in 3D doesn't touch the signal.
The pixel map doesn't end at a file. From Stage View you can send it to the network as an NDI source or push it out to a connected monitor — at rehearsal, without exporting and dragging files around.
Stage View · Output 1
e.g. Resolume, TouchDesigner, vMix, OBS with the NDI plugin
Borderless window on the chosen monitor, always on top
In the screen panel you choose an output and broadcast it to the network. The frame has the resolution of the output, and the pixel map sits in it exactly where it does in the Outputs tab. Mode “Whole output” or “This screen only”.
COMPUTER-NAME (Project — Output)Send an output to a connected monitor — e.g. straight to an LED processor. “Fit to display” scales while keeping proportions, and “1:1 pixel for pixel” lets you check the sharpness of the mapping. You turn it off with the button or the Esc key.
Marked cabinet quarters are visible in NDI and on the monitor too. The crew sees right away which modules to check — no need to describe them in a chat.
NDI requires the NDI Runtime to be installed (it comes with NDI Tools). When it's missing, the NDI section says exactly what it is looking for. The rest of the app works without it.
Every export opens the system's save dialog. You save a full set of screens at once, asked for the folder only once.
Stage View, a whole output at full resolution or a single screen's pixel map. A full set saves to one folder.
Pixel maps as vectors — a separate file for each output, ready for further work in a graphics program.
The pack list and the “Technical report” — an event summary with screens, circuits, signal outputs and notes.
Ready-made slices with the chosen input and output, to load in Advanced Output — no manual mapping.
Signal Flow (a whole output or a whole screen, including one cut across several outputs) and Power Flow (per screen) to PNG, with output and circuit numbers on the pixel map.
The whole project in one file: you save with ⌘S, and load on another computer with ⇧⌘O. Project files (zip) are part of the Team plan.
Event name, date and venue. You can have as many projects as you like and duplicate them.
Projects · ⌘NAdd screens and lay them out in 2D; in 3D, position them by dragging the axis arrows or typing the position in millimeters.
Stage ViewAssign screens to outputs, cut them where needed and check the cabinet numbering.
OutputsDraw paths along the cabinets and watch the output and circuit limits before you arrive at the venue.
Signal · Power FlowConnection diagram, pack list, PDF report, exports — and NDI or a monitor at rehearsal.
Device Map · Pack ListThis is the calculation Signal Flow and Power Flow do in the app — here in a short version. Pick a cabinet, enter the wall size and see how many processor outputs and power circuits you need.
Click the cabinets in order, the way you draw a path in Signal Flow. The bar shows how many pixels a single processor output carries.
The app is local-first: the project you work on is always on your own disk, so it works the same in the office as at a venue with no signal. Sign-in and optional cloud sync work on top of that — without taking your projects off your computer.
Designing never needs a connection. You sign in once and then work offline for up to 30 days between check-ins, with a countdown of the days left.
Projects are saved in a local SQLite database — only changes are written, with automatic backups. The data is encrypted on disk and bound to your computer.
Projects sync in the background while you keep working locally. On a new computer you sign in and your projects come back.
Pixel maps, signal paths and power circuits with limit checks — before the first cabinet goes on the truss.
Ready pixel maps, Resolume XML and NDI output, so you can load content before the wall even lights up.
Dashboard, pack list and PDF report in one place — for quotes, riders and crew briefings.
Custom modules with power and resolution, saved device templates and quick project variants by duplicating.
The details that make everyday work quicker — from saving and undo to the biggest walls.
Only changes are written, so saving stays quick even in large projects, and backups are made automatically in the background.
Undo and redo buttons on every editing page. The history is kept per project and survives restarting the app.
Lock the list when it's final and unlock it to edit, add items with a row at the bottom of each table — and extras are saved instantly.
Bad pixels and Remove cabinet are separate, exclusive modes. One click switches to the screen and acts right away, and the middle mouse button pans the view.
Color pickers and color changes stay smooth even on walls of 50 × 25 cabinets, and adding an LED screen takes just a moment.
The Programming section of the sidebar — Stage View, Outputs, Signal Flow and Power Flow — is always visible.
LED Event Manager launches with its first production release, 1.0. This is what comes with it from day one — alongside everything else on this page.
Sign in once, then keep working offline for up to 30 days between check-ins. A countdown shows how many offline days are left. One license is active on one computer.
Try the app for 7 days: up to 3 screens and 2 outputs per project, no exports, and the pack list stays locked.
Local-first: you work on the copy on your computer and projects sync in the background. On a new computer, sign in and your projects come back.
Shared team projects and project files you can import and export as a zip — for example to hand over on a USB stick. Part of the Team plan.
Three ways to use the app. Pricing will be announced with the 1.0 release.
7 days, free
For one person
For crews · several seats
Pricing will be announced with the 1.0 release. Planning for a team? Write to us.
You need an account, but not a constant connection. You sign in once, and after that the app works offline for up to 30 days between check-ins.
A countdown shows how many offline days you have left, and designing itself never needs a connection.
Release 1.0 runs on macOS (Apple Silicon). A Windows version will come in the future.
Yes — the app comes with a 7-day free trial. During the trial you can have up to 3 screens and 2 outputs per project, exports are turned off and the pack list is locked. When the trial ends, your projects stay safe on your computer; choose a plan to keep working.
Individual is for one person: all features and cloud sync of your own projects, without project-file import and export. Team has several seats and adds shared team projects plus project-file import and export as a zip (for example to hand over on a USB stick) — on top of everything in Individual. Pricing will be announced with the 1.0 release.
The app is local-first: you always work on the copy on your computer, and changes sync in the background. On a new computer you simply sign in and your projects come back.
A license is active on one computer at a time. Cloud sync is included in both the Individual and Team plans.
The app needs to check in with your account at least once every 30 days. Connect to the internet and the offline period starts again from 30 days. The countdown in the app shows how many days are left, so you can check in before a job at a venue with no signal. Your projects stay on your computer the whole time.
You select a screen and grab its handle: the X, Y and Z arrows move it along one axis, the square moves it across the floor, and the orange ring rotates it around the vertical axis (in 15° steps with Shift). The position rounds to 10 mm, and a plain click moves nothing.
You can enter the same values in the screen panel: X, Y, Z in millimeters plus pitch, yaw and roll in degrees. The Reset button returns to the 2D layout.
Only for NDI output. This feature uses the NDI Runtime, installed together with NDI Tools, and detects it on its own. If it isn't there, the app tells you what it is looking for; all the other modules work without it.
In the Add screen dialog you define a cabinet: a name, the size in millimeters, the resolution in pixels and the power per piece. You can save it so it comes back for further screens. The power is useful in Power Flow, because that's where watts are counted.
Yes. Every screen has a position in millimeters (X, Y, Z) and a rotation on three axes, so it can hang from the ceiling, lie on the floor or stand at an angle. The MotoExpo and TechFair projects on this page are examples. You position them with the handle on screen or by typing the position in the panel.
In a local SQLite database in the app's data folder, with automatic backups. Only changes are written, and the data is encrypted on disk and bound to your computer.
With the Team plan you can also export a single project as a zip file and import it on another computer; with Individual, your projects move with you through cloud sync.
The app launches with release 1.0. Write to us to get it, open a project and see what your stage looks like in 3D before you head to the venue.
