Timeline (BETA)

The Timeline allows you to stage audio files to play at specific times in relation to one another. You can place the files on separate tracks; each track going to a different output, or you can place the files end-to-end on the same track. You choose the audio files from those stored on the Core in the Messages, Preambles, and Audio subdirectories. Manage files in these directories using the Q-SYS Core Manager > Audio Files page.

Note: This is a BETA component. Though it is functional, it is not feature complete and is subject to change.
