Live Inputs, Dynamic Effects

The new audio engine in QLab 3 lets you apply audio effects to your files and mic inputs—in real time. You can even fade the parameters of those effects to create dynamic, reactive designs. Learn more...

Surfaces, Not Screens

QLab 3 lets you abstract away the details of which projector is where, freeing you up to focus your design on the surfaces you're painting with projections. Learn more...

Audio Effects

You can now apply live audio effects to all your cues: EQ, pitch shift, reverb, and more. Add audio effects to individual cues, across all cue outputs, or even on your device outputs.

Dynamic Effects

The powerful new Fade Cue can adjust your audio effect parameters in real time. It can even adjust playback rate, to dynamically speed up or slow down your audio, with or without pitch shifting.

Live Audio Inputs

The new Mic Cue offers up to 24 channels of live audio inputs. Plus all those routing, fading, and audio effects you get on Audio Cues? You get those on Mic Cues too.

It slices, it dices

Every file can now be sliced into an unlimited number of sections, and each slice gets its own loop count. If your audio files have markers, QLab will automatically import those as slices. Need multiple vamps in one piece of music? It can't get any easier.

Up to 24 channels per file

Increased from 16 channels, by popular request.

Text-based level matrix

Setting precise volume levels is now easy at any input, output, or crosspoint. Navigate from cell to cell with the arrow keys for fast volume entry. And don't worry, you can still set volumes by clicking and dragging.

Built-in edge blending

QLab can automatically calculate edge blending for each overlapping projector in your surface.

Keystone correction and corner pinning

You can use corner pinning to adjust each projector in your surface.

Support for multi-output video devices

Using surfaces, you can now easily address individual outputs on multi-output video devices such as a Matrox DualHead2Go or TripleHead2Go device.

Unlimited slices per file

Just as with Audio Cues, you can now slice Video Cues into unlimited sliced sections, building as many loops within your video as you like.

Relative animations

Ever wanted to nudge a group of video cues up or down, or rotate them all at the same time? Now you can, with a single Fade Cue.

Adjustable playback rate

Adjust your video to run faster or slower.

Output masking

You can add a mask to any surface, and all cues sent to that surface will be appropriately masked. In the mask image, use white where you want video to show, and black where you want to mask it.

An extensive set of built-in video effects

Have fun.

Better Quartz Composer Integration

If you're a Quartz Composer expert, you can create your own effects, and QLab will allow you to manipulate the inputs you publish.


You can now easily send any OSC message over the network. Connecting multiple QLab machines together has never been this simple.

OSC remote control

QLab now has an extensive OSC-based API for controlling it over an IP network.

New logic gates on MIDI triggers

You can now use "greater than" and "less than" operators to specify when cues should trigger from incoming MIDI signals. For example: "trigger this cue when any NOTE ON message is received with a velocity >10"

Text search

You can now easily do a full text search on your cue list. QLab will search the cue numbers, names, filenames, and notes for your search query, and highlight all matching cues.

Preview your work in the audition window

When the audition window is open, all newly triggered audio and video cues will play to the audition window. Build a complex multi-projector video workspace on your laptop even if you don't have the projectors.

Broken cues & warnings view

Quickly and easily review any issues in your workspace. March through the list of each cue that needs attention, fixing as you go.

Flag your cues

Flagging a cue makes it easy to come back later for any necessary adjustments. Flagged cues also appear in the "Broken Cues & Warnings" view.

New panic action

Pressing "escape" now invokes the new panic action on all cues, allowing you to quickly but gently fade out undesired audio and video. A second hit on the panic button will immediately stop everything.

Edit and Show Mode

QLab 3 now has two distinct modes: "Edit" and "Show". Switching to show mode locks the workspace and presents a simpler interface for easy show operation.
