QLab Pro v3.0.17 (Mac OS X)
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.
Rigorously engineered for first-class performance. QLab uses Apple's low latency CoreAudio framework to provide playback control accurate to a thousandth of a second. QLab can also guarantee sample-accurate audio and video synchronization across all the cues in your workspace. And by taking advantage of Apple's Quartz Composer technology, QLab allows you to completely customize video rendering in each cue, applying image filters and more.
QLab makes it simple to create rich multimedia designs for live performances and installations. From Broadway to the West End, in churches, museums, store fronts, concert halls, and theaters around the world, people use QLab to bring their audio and video to life.
Using building blocks called "cues", you can create sophisticated designs in seconds. Getting started is as simple as dragging in a file and pressing "GO". From there, add commands to fade volume, animate videos, or add audio and video effects.

What's New
Version 3.0.17:
A bug that could cause camera cues to quit unexpectedly.
Pass time to Quartz compositions from camera cues.
Smart quotes (new in 10.9) are now replaced by dumb quotes for script cues, because AppleScript barfs on them. (Of course it does, it's AppleScript, why be reasonable when you can fail mysteriously for dumb reasons.)
Optimize loading to reduce the time it takes to load audio and video cues.
Slightly delay auto-loading of the next cue sequence, to improve response times when starting cues.
A subtle bug in the precedence of load operations; fixes some unusual pre-loading scenarios on a sequence of cues.
A multitouch bug that could cause phantom changes in a draggable text field that has keyboard focus.
A bug that could cause certain kinds of devamp cue sequences to fail, e.g. a series of devamp cues that each trigger the next.
When capturing a MIDI Voice Message, only listen for messages on the MIDI channel specified in the workspace settings.
Update the error message on the script cue inspector when it runs, in case that is the first time we've noticed an error (e.g. when previewing the cue).
Don't live-preview a fade when changing the fade cue's target or duration.
When zooming in/out on an audio waveform, anchor the zoom on the mouse location if the mouse is in the view.
Ask for confirmation if you try to quit while a cue is currently running.
Transparent background option for Syphon output.
