Powerful and intuitive show control for your Mac.

QLab makes it simple to build rich, sophisticated multimedia designs for theatre, dance, or other live performance or installation projects. Use it for sound design, video projection design, or anything where you need to trigger media playback in a precise and flexible manner.

Focus on your art. Leave the rest to QLab.

QLab allows you to control audio, video, and MIDI from a single workspace. And while QLab can control racks of state-of-the-art equipment, you don't need high-end hardware for professional results. Make it the centerpiece of your tech booth or turn your iBook into a portable cueing powerhouse.

The basic version of QLab is absolutely free, and comes fully loaded with dozens of sophisticated features. In fact, you'd have to spend hundreds of dollars on other software just to get what QLab gives you for free. For advanced users, additional plugins and enhanced features are available.

Designed to enable you, not get in your way.

QLab provides an intuitive environment for crafting your design. Organize your cues simply by dragging and dropping them. Want to add a new sound? Just drag it onto your workspace. Cut and paste cues to new locations, new workspaces, or even external spreadsheets. Decide you didn't like that adjustment? No problem, you can undo anything.

QLab keeps every parameter for every cue right at your fingertips. It's easy. Like any self-respecting Mac software ought to be.

Rigorously engineered for first-class performance.

Designed for precision, QLab provides playback control accurate to thousandths of a second. It uses pre-buffered sounds and Apple's CoreAudio framework to ensure your audio plays instantly. If you have more than one CPU, QLab will automatically balance the load across processors. And QLab doesn't place any artificial limits on your creativity, like some show control software. Your Mac is capable of running dozens of cues at once. Who are we to get in its way?
