Dynamic Audio Effects: Built-in Audio Unit (AU) capabilities for applying audio effects to individual cues, cue outputs, or even audio device outputs.Up to 24 Audio Inputs / 48 Audio outputs per Cue.In later installments, we will look at video and show control. Used in applications from Broadway to Britain’s West End, churches, museums, art installations, and more, QLab makes it easy (and affordable) for anyone to put together rich multimedia designs for live performances and installations.įor this review, I would like to talk a bit about the new audio tools available in Version 3. In a span of roughly 7 years, QLab has evolved from a sound playback program for Mac OS X into an industry standard show control platform featuring a robust package of functions, featuring cue-based sound and video control, MIDI and OSC integration, video and audio effects plug-ins, surface-based video output for projection mapping, and more. This first installation covers the newest version of QLab* recently released in May 2013. Like the blog itself, it is my intention to cover a wide range of products, both new and old, that have made my work easier. By default, a cue is triggered by clicking a large GO button on the screen, or by pressing the space bar.Welcome to the first of an ongoing series of product reviews I will be running on here. After doing so, an untrained user can run the software in a playback situation. The designer of a cue sheet can save their show file, and lock it, preventing any changes to the cues. Live playback Ī key software feature with QLab is its ease of use in live playback situations. MIDI signals can be sent to QLab from other computers running QLab software, or any other MIDI capable device, using a MIDI Interface. The software also accepts MIDI signals as triggers for its own cues. QLab allows MIDI signals to be sent as a cue to trigger other devices, such as digital audio consoles. It is useful to note that the speed of the computer processor and video card can affect the quality of video playback. The designer can also select on which video card or cards the video will play. Video files can be altered in real time in QLab, by integrating a Quartz Composer file. The video capability of the software in its most recent version allows a designer to add video files to their cue lists, allowing them to be time aligned with other cues, including audio files. Audio cues can also be placed into groups, so that multiple files can be triggered at one moment. Once the audio files are inserted into the cue list, the end-user can then manipulate it by looping it, changing the amplitude or volume, and adding fades in or out. QLab allows an end-user or designer to align audio files in a sequential order. The list of available cues in v4 is as follows: When triggered, a cue executes an operation. In QLab, a cue is a marker for an action to take place in the program. As of June, 2021, the most recent version of QLab is 4.6.9. As with Version 3, a new edition of the QLab book was released called QLab 4: Projects in Video, Audio, and Lighting Control, by Jeromy Hopgood. This new function allowed QLab to function as a lighting console. As with previous versions, this one added many new user functions, including the addition of lighting cues. In 2016, Figure 53 released the newest major version of QLab, version 4.0. 2013 also saw the publication of the first book dedicated to the use of the software, QLab 3 Show Control: Projects for Live Performances & Installations, by Jeromy Hopgood (not affiliated with Figure 53, LLC). 2013 marked the release of QLab Version 3.0, with a wide range of new features, particularly in the realm of audio and video effects, Syphon video, the addition of microphone cues, and integration of OSC capabilities. In January 2009, Version 2.0 was released with a complete visual makeover of the interface and new control features. QLab 1.3.10 was the first version of the software and was released on May 25, 2007.
