L.E.D. Lab2.32
Publisher Description
L.E.D. Lab is the quickest, easiest, most powerful way to drive your LED display! Custom programming is no longer required to get up-and-running. It is ideal for artists, professional display designers, architects, VJs, lighting designers, hobbyists, and anyone wanting to add a little animated color to their sculpture, art car, home, business or wardrobe.
L.E.D. Lab allows you to create a list of Scenes, which can be played back in order or shuffled. There are currently two kinds of Scenes:
● Pictures Scene - A montage of still images, videos, and live camera feeds is designed. The position, velocity, rotation, size, and coloring of each picture can be animated. You can use your own photos and videos, and the iPad camera. Rendering to odd-shaped displays is made possible with photographically-generated map files.
● Strips Scene - Particles of color are sent down each strip. The velocity, hue, saturation, and brightness of each particle can be animated.
Other features include:
● Music - Create lists of Tracks. Each track plays a song from your music library, along with any number of Scenes. You can elaborately choreograph a song, or let the Scenes play in random order.
● Audio Reactivity - Any animatable parameter may be controlled by the amplitude of audio in a specified frequency range.
● External Control - Any animatable parameter may be controlled by MIDI, DMX, ArtNet, or OSC.
● Color Keying - An image, video file, or live video feed can be made selectively transparent, making it easy to mix in with other images.
● Tiling - Any image, video file, or live video feed can be tiled in any or all directions, with adjustable spacing and fade-out.
● Display Modes - Editing can be performed with or without the LEDs connected. The editing UI can also be hidden, allowing operation in a "kiosk" mode.
So what kind of LED display can you make with L.E.D. Lab? Some Examples:

Any iOS device can be used to play Scene Lists. An iPad is best for full editing.
L.E.D. Lab works with the following LED controllers:
● PixelPusher (our favorite)
● Art-Net
● sACN
● DDP/Minleon/TekLights
● RGB-123
● FadeCandy/FCServer
● OpenPixel
It can also display to an external monitor or projector, serving as a VJ app.
Extensive help information is provided for the rich user-interface:
● Help Explorer - Displays help text for any knob, slider, button, popup, list, or view inside a magnifying glass you drag around the screen. (See this in the last screen shot.)
● Help Topics - Little chapters to read about some of the more detailed functionalities.
● Help Tutorials• fixed some issues around the "Undiscover" feature in the LED Setup screen.
• In the "DMX" section of the LED Setup screen, you can now specify that the RGBW data be sent to multiple bytes in the DMX channel stream. This is useful for DMX floodlights and other non-LED-strip DMX devices.

Aug 14, 2022 Version 2.18

version 2.16

May 12, 2022 Version 2.16
• When new images and videos are added to LED Lab's documents folder, they now automatically appear in the UI.
• The default size of the bitmap used to render embedded Scenes is now half of what it was, leading to much faster rendering.

version 2.14

Oct 24, 2021 Version 2.14
• When the current track is tapped, it is no longer re-started.

• When a Track's scenes are manually shown or hidden, "Auto-Show Scenes" is turned off.
• Flicking to scroll the Track Editing scene list sometimes would result in a scene being dragged. This has been fixed.
• Some audio hardware causes a large delay when starting up. This would sometimes cause the audio of a Track to lag behind its scenes. Now, the audio system is kept running so that these delays are not an issue.
• When the Track "Gap" was non-zero, the next Track's audio would be started twice. This would result in an audio glitch and cause the audio of a Track to lag behind its scenes. This has been fixed.
