Hi
This is my bad. I confused the qlab one on the add-ons page with a one for isadora/eos.
But, if you peruse the links posted by Woland above, there is a treasure trove of information, guides and files to achieve the aim of using OSC to control lighting cues on the eos consoles.
I read through those links and ,as usual, leant more than I thought I knew! I would start with those guides and Marks Guru session on OSC. I am sure ETC has OSC guides on their sites as well as having a healthy forum akin to here. One of the links gives a very detailed step by step set up guide here.
You do not need the console but could practice this set up with 1/2 computers. Once they are speaking via network, then you could play with the command syntax and be ahead of yourself before you enter the venue. The venue lighting staff should be up to speed with this approach as it has become a very normative practice in the industry.
You are only sending a simple GO command to eos at the end of the day. You can specify the number but the syntax is very straightforward etc. Once you have the first one down, then it should be a simple rinse and repeat.
