 This guide will show you how to set up QLab to play a single audio file each time a button is pressed.
-You could use the [[products:the_big_button|The Big Button]] or [[products:the_button|The Button]] for this, or any of the our other products with multiple buttons if you wanted to expand this to multiple sounds.

+(This guide assumes your device is programmed as a USB MIDI device and set to send a noteOn MIDI event.)

+You'll need to load the audio file into QLab.

+(Make sure you save your workspace as you go!)

+If you are not in **Edit** mode click the Edit button in the bottom left corner and the click on your audio file to show the bottom pane of the window and then click on the **Triggers** tab.

+Click the checkbox for **MIDI Trigger** to enable it and make sure **Note On** is selected in the drop down menu next to the checkbox.

+Click on the **Capture** button and get ready to press...

+{{:usage:qlab-play-single-file-07.png?direct&900|}}
+When you see **Waiting for MIDI...** you can press the button on the device.
+----
+{{:usage:qlab-play-single-file-08.png?direct&900|}}
+After you press the button it should show the **Note** and **Velocity** sent from the device.
+//(Note: If this doesn't work we may need to check that the device is showing up properly in QLab. We'll add another guide for that.)//

+{{:usage:qlab-play-single-file-09.png?direct&900|}}
+You can now change from **Edit** mode to **Show** mode using the buttons in the lower left corner.
+Typically with a cue list you would need to highlight an item in the list to start things...
+----
+{{:usage:qlab-play-single-file-10.png?direct&900|}}
+But since we've created a trigger for this specific file you can just press the button to play the audio and you don't need to highlight the file first.
+----
+{{:usage:qlab-play-single-file-11.png?direct&900|}}
+You are all set! Press the button to play the sound.
+The advantage of using a device programmed for MIDI is that QLab does not need to be the frontmost application to capture keystrokes from a computer keyboard. As long as QLab is running (and configured) it will play the sound.
+Don't forget to save your workspace!
