Controlling QLab Using Isadora Via OSC

In this tutorial, we will explore how to use Isadora to control QLab using Open Sound Control (OSC). This technique is particularly useful in theatrical situations where you need to trigger QLab cues remotely without having multiple operators. With QLab and Isadora working together seamlessly via OSC, you can streamline your production workflow and reduce the number of people needed to run a show.

Getting Started

To begin with, you will need to have both QLab and Isadora running on the same computer or connected via a local area network using Ethernet cables and a network switch or router. If you are running QLab on a different computer than Isadora, make sure that the computers are properly networked.

Once you have set up your system, open the example file and User Actors for controlling QLab from the TroikaTronix Add-Ons Page. This will provide you with a comprehensive starting point for setting up your OSC connection between Isadora and QLab.

Setting Up QLab

In QLab, navigate to the 'Settings' window by clicking on the gear icon at the bottom right of the screen. Select the 'OSC Controls' tab from the list along the left-hand side. This will allow you to configure the OSC settings for your QLab installation.

Next, find the IP address of the computer running QLab and input it into the 'IP' input of the QLab Set Global IP & Port User Actor. If you are using QLab on the same computer as Isadora, you can leave this set to 'localhost'.

Setting Up Isadora

In Isadora, open the User Actor in the top left corner: QLab Set Global IP & Port. This will allow you to configure the OSC settings for your Isadora installation.

To find the IP address of your computer, look just above the QLab port information. The ports that QLab uses can be found just above the 'Command' section.

Triggering QLab Cues

Once you have set up both QLab and Isadora, you can use Isadora to trigger QLab cues by sending messages over OSC. This is a powerful technique that allows you to control QLab remotely without having multiple operators.

In Isadora, create a new User Actor and select the 'QLab Cue Controller' option. This will allow you to start, stop, and select cues in QLab using Isadora.

Controlling QLab using Isadora via OSC is a powerful technique that can greatly simplify your production workflow. By following the steps outlined above, you can set up a seamless connection between your QLab installation and Isadora, allowing you to trigger QLab cues remotely without having multiple operators.
