The green numbers which appear along the bottom of the waveform view are play counts for each slice. A section of the cue between two slice markers, or between a marker and the start or end of the cue, is a slice. A green marker, called a slice marker, will appear. To create a slice, click in the waveform view and then click the Add Slice button to the left of the waveform, or use the keyboard shortcut M. To do this, you create slices within the cue and set each slice to loop as needed.

The Play count and Infinite loop options can loop the entire sound file, but QLab can also loop specific sections of the file. You can zoom in and out using the + and - buttons to the right of the waveform, or by scrolling vertically. The center of the Time & Loops tab shows a waveform view of the target audio file. Starting with QLab 4.1, these options are available whether or not the cue contains slices. Alternately, you can select Infinite loop, right below Play count, to loop the sound indefinitely. You can change the play count to any whole number to loop the sound file that number of times. The default is 1, meaning that the sound file will play once through and then stop. Play count is the number of times that the sound file will be played when the cue is run.

You can click in waveform view, or preview the cue and then pause it, and then use the keyboard shortcut ⇧I (“I for in”) to set the start time, or ⇧O (“O for out”) to set the end time.

You can drag the start and end time markers, which are downward-pointing grey triangles at either end of the waveform view.

You can type values into the start time and end time text fields.

You can set the start and end times in three ways: The Basics and Triggers tabs are the same for all cue types, and you can learn more about them from the page on the Inspector in the General section of this documentation. When an Audio cue is selected, six tabs will appear in the Inspector:

MP3 (Because MP3s have inherent timing problems, we do not recommend using them.).

All Audio cues within a sequence play in sample-accurate sync as long as they’re assigned to the same output patch.Īudio cues may target any file type supported by Core Audio, Apple’s audio framework, but we recommend the following types: When an Audio cue is triggered, it begins playing its target file. Audio cues must have a target, which is a sound file on your computer, and an output patch, which is a sound output destination such as your computers’ speakers, headphone jack, or an audio interface. Audio cues allow you to play sound files with precise control over timing, levels, and routing.
