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

So much Creative Power

I have used this app and pixel pusher hardware for years and it just keeps getting better. Every time I think to myself... “I wish I could do______ with my light installation” I find a new menu or an update that expands the already impressive capability of this app. So much thought and attention to detail keeps me inspired and pushing my creativity. Chris has also promptly responded to countless emails to help me in the darkest times to get me back on track. Steep yet intuitive learning curve but the more time you spend with the app the more you realize just how powerful it is.

Not for the faint of heart

This is NOT a simple program - it will take no small amount of trial and error to get things set up the way you want them - but once you've got it set up, it's an AMAZINGLY rich and flexible resource. I've used it with a Fadecandy-based Neopixel matrix as well as with RasPi-based HU75 matrices (both emulating PixelPushers), and it's been great with both.
(And in addition to that, the author was very helpful via email in working out specific settings tweaks to get me up and running.)

Great software and great ongoing support

I have been using the software with my PixelPusher since 2015. I left my unit hardware sit for a couple years and when I tried to get it working again with L.E.D. Lab I ran into problems. Christopher gave me great support in helping me get the hardware up and running. Now the software works like a charm. Love it when you deal with real pro's.
