QLab allows you to control audio, video, and MIDI from a single workspace. The basic version of QLab is free and provides a powerful audio playback environment. For advanced users, licenses are available to enhance the audio features, as well as to add video and MIDI functionality.

Designed to make you faster. We’ve worked hard to create an intuitive environment for crafting your designs. Need to trim the head and tail of that cue? Just bring up the waveform editor and drag your start and end points. Want your video flipped horizontally and centered on the second projector? Click, drag, done. Cut and paste cues to new workspaces or even external spreadsheets. Decide you didn’t like that adjustment? No problem, you can undo anything.

What is QLab?
QLab® runs shows of all sizes, all over the world. From intimate storefront theaters to televised events reaching billions of people across the globe, QLab is the tool designers trust to make their live shows come to life. Flexible, reliable, and easy to learn, QLab is the industry standard for a reason.

What does QLab do?
QLab makes it simple to create intricate designs of light, sound, and video, which you play back during a live performance.
QLab allows you to lock in exactly how you want the light, sound, and video to play during your performance. When you’re done designing, you’ll switch to “show mode” and run your show just by pressing “GO”.

What makes QLab different?
QLab is designed specifically to handle the needs of live events, like theater. The person running the show each night can react to what is happening on stage, such as waiting for a scene to finish before they trigger a scene transition, or even to handle the case where a performer accidentally skips a few lines and jumps ahead. QLab can react dynamically to what is happening on stage, or it can be programmed to play back precisely the same way every night. Most shows will be a mix of both.

Who uses QLab?
There’s a good chance you’ll find QLab in your favorite local theater. You’ll also see it on Broadway, the West End, and in churches, sports stadiums, and museums. From high school students to seasoned pros, QLab is what they use to make the show go.
