Exeldro Mar 28, Palakis Jun 1, Xaymar Nov 3, Tuna Jan 12, QLab 3 can interact with Quartz Composer in one of two primary ways; as a custom Video Effect or as an external application which uses Syphon to send information to or from QLab. Both of these instances will be covered in this Tutorial. Quartz Composer is a graphic programming environment that allows you to build and run custom video filters, effects, transitions, and more.

First off, most Quartz Composer needs can be handled with the built in effects provided with your version of QLab 3. Simply navigate to the Video Effects tab in the Inspector, click the radio button and select the effect type you want.

Adjust the sliders as desired. If you want to animate that effect simply add a Fade Cue targeting the media you added the effect to and adjust the values and duration accordingly. This is great for basic effects in a tech situation where suddenly you realize it would all look way better if black and white or perhaps you want to add a simple pixelate or blur effect to a transition. However, sometimes you will want a more complex transition.

Perhaps you want to start with a whiteout overexposure that is blurred in black and white and slowly resolves into a full color clear image.

Well, then you will need to build a custom Quartz Patch. But don't worry, it is frighteningly simple. Quartz Composer is provided for free with Apple's developer tools in X-Code. When you first open Quartz Composer you will be presented with a blank Composition as shown in the below screen shot. The Clear patch clears the frame buffer of any renderers and is not necessary for image filters so you can simply delete that.

Now you have a blank canvas. What you will need in order to build an image filter for QLab is a composition that has published inputs and outputs for the media you will play back. You can download this sample file that when opened should look like the below screenshot. Your next step will be adding patches.

Controlling Procedural and Physical Modelling Plug-Ins

Over on the screen left side you will see your Library. This contains many patches and filters pre-built. Simply drag and drop the filters into your composition and connect the image output right hand side of a patch with an image input left hand side of the patch. This will build your rendering path that each frame goes through.

Once you are done with that you will probably want to have control over these values within QLab. To do this you will need to publish additional inputs.

Don't worry, this does not involve getting an interview with Random House, it is just a mouse click. Control-Click on one of your patches. This opens a dialog box with a few options. Navigate to Publish Inputs and select one, perhaps the radius parameter on a blur patch. Keep doing this until all the parameters you want control over are published. Now when you load this patch into QLab you can control all these parameters directly from within QLab.

For every parameter that you publish you will probably want to add an Input Splitter.

This is another option in that Control-Click dropdown. Once you have added each of your splitters select the splitter and look at the Inspector within Quartz Composer.

Even though Quartz Composer accepts NaN for an unlimited value QLab seems to like real numbers so go ahead and enter them no, really, do it - as in, none of your parameters will work in QLab 3, even if only one parameter does not sport min and max values.Here is a screen recording of a fully pimped-out QLab 3 installation with probably more cue output and device output plug-ins than are sensible.

View this full screen! With version 3, QLab opened itself up to the world of third-party AudioUnit plug-ins. The downside of allowing third-party plug-ins to directly interface with QLab is that some plug-ins will work better than others, and some will not work at all, and it can be difficult to discern the reasons.

It should also be noted that the way QLab uses plug-ins on cues is somewhat more complex than when plug-ins are used in a DAW. In the DAW they are generally loaded when a session is opened, either as channel inserts or on aux busses, and stay loaded. With QLab, when used within cues, they are loaded and unloaded with the cues, which comes with a unique set of benefits and drawbacks. The best policy is to use the simplest plug-in that will do the job you want at the quality you require.

Some plug-ins require very high CPU loads which can affect the performance of your workspaces. Some will cause very nasty clicks and bangs on output.

There are a lot of repetitive examples, but if you work through them you will potentially save yourself hours of frustration in trying to work out why plug-ins are not working as you expect. This is not unique to Waves.

Other plug-in manufacturers have similar lists of supported DAWs. If you intend using Waves plug-ins and many users of QLab do then it is recommended that you authorize your Waves licenses to a USB key. Using Waves plug-ins requires QLab version 3. Audio plug-ins in cues have no metering capabilities regardless of what meters are built into the plug-in. If you need meters, then insert the plug-ins in cue or device outputs as explained in Example 8 below.

More often than not, this will result in this window stealing keyboard focus, meaning the keyboard will no longer operate QLab.

Clicking twice on the selected cue will give keyboard focus back to QLab. In the screen recordings in the examples on the following pages, some vital details are quite small.

It is a good general purpose reverb.

Here it is in QLab applied as an audio effect on an audio cue:. The first thing to note is what happens if you stop the cue by panicking the workspace. When working with plug-ins you may have to press the escape key twice in rapid succession to stop Audio cues with effects applied. At the end of the audio, the cue stays active with the tail-out indicator present for ten seconds or so, even though the reverb tail is only about two seconds.

This could be problematic.When all you have is a Chromebook, everything looks like an Android-shaped nail Importing, exporting, and understanding slice markers.

Filter by Tags Show Tags. Advanced Programming. External Tools.Up to this decade recorded sound effects for the theatre have, in the main, been derived from recordings of the actual noise making animal, mineral, or vegetable, or a recording of an imitation of a realistic effect, made by other means.

In physical modeling, the characteristics of any instrument are distilled into mathematical formulae which can be manipulated to produce an amazing range of transformations within a single model. In response to the needs of the computer gaming industry, these modeling techniques have been applied to sound effects generation, including atmos, foley and spot effects, and those engines are now being made available as standard audio plug-ins for DAWs.

This is a new frontier in theatre sound effects design, and one we may all need to explore and gain proficiency in. Most of these plug-ins have been designed with the needs of video and film post-production foremost. The controls have very fine resolution and are designed to be recorded as lane based automation data in timeline based DAWs.

This chapter looks at how we can best use these plug-ins in a non-timeline based system, like QLab. This plug-in models a variety of jet engines, flying in a simulation of a real-world environment.

It is available on a 7-day free trial to see if it is useful in your workflow. TURBINE offers 4 channel output and many plug-ins of this type will be used to their best advantage in multichannel environments. The standalone will support as many outputs as your interface provides.

There is no problem with running the Standalone version of Plogue Bidule at the same time as QLab, and both programs can share the same outputs, on the same audio interface without difficulty. Monitor carefully.

Controlling Procedural and Physical Modelling Plug-Ins

Launching Xcode If nothing happens, download Xcode and try again. Latest commit.Physical modeling is a process of simulating the actual physical properties of a sound-making object or environment. With physical modeling, the characteristics of a musical instrument are distilled into mathematical formulae which can be manipulated to produce an amazing range of sound.

For a guitar, the shape of the body, the type of strings, any fingering position, and even the simulated amplifier and simulated microphone can all be derived from the model and controlled inside the DAW, without needing to have preemptively sampled all these variations. Up through the first decade of the 21st century, recorded sound effects for the theater have mostly been derived from recordings of actual animals, minerals, or vegetables.

In response to the needs of the computer gaming industry, however, physical modeling techniques have now been applied to sound effects generation, allowing the generation of atmospheric, Foley, and spot effects on demand, and without the needs for sampling. These sound generation engines are now being made available as standard audio plugins for DAWs.

This is a new frontier in theatrical sound effects design, and one we may all need to explore and gain proficiency in. Most of these plugins have been designed for use in video games, television, video, and film post-production workflows.

The controls have very fine resolution and are designed to be used in timeline based DAWs with automation recording capabilities. This chapter looks at how we can best use these plugins in a non-timeline based system like QLab.

This plugin models a variety of jet engines, flying in a simulation of a real-world environment. It is available as a 7-day free trial to see if it is useful in your workflow. These plugins are categorized as music devices, rather than audio effects, and therefore are not directly available inside QLab.

This opens the door to some very advanced techniques which are discussed in the AU Instruments in QLab chapter of the cookbook. There is no problem with running the standalone version of Plogue Bidule at the same time as QLab, and both programs can share the same outputs on the same audio interface without any problem.

Warning: This is quite a large video file about MB. A very loud jet engine passes in the second half of the video. Watch your levels; keep you hand on the volume knob.

In the second half, QLab is recording pan positions in the Simulation tab, then recalling those positions while modulating the Engine tab. The end result is a simulation of a jet engine aircraft passing by as it accelerates. A common way of controlling parameters in plugins is with MIDI control change messages.

These are generally 7-bit controllers with steps between minimum and maximum. You may be able to predict what will happen when we try to control something that has a much wider frequency range than a piano:. We can clearly hear the almost semitone steps as the controller moves from one value to the next. IAC stands for inter-application communication, and bus is just a metaphor.
