It depends on the amount of replications and this is such a deep technical question that we really have to dive deep into the codebase to figure this out for you 
For example I dont know or JavaScript code that is in memory needs to be re-initiliazed.
@woland thanks for this. I've got OSC>OSB working on my Mac but when I try to run it on a PC (which will be used for the installation) the messages are not getting through.
I've set the OSC port in Isadora Prefs to 3333
When the osc is sent using your user actor the OSC out in Isadora UI flashes
I've got the connection from OSC>OSB app working with a green light indicator in the UI
Enable Websocket server enabled in OBS Tools>Websocket Server Settings
Any thoughts on what I've missed?
Many thanks

 You could contact them and ask. They might tell you.

@ril We just saw a pretty big show in Montreal. It was a destination for our visit last weekend. There were three galleries, one huge and two smaller. All of them used all four walls and the floor. One of them had motion tracking on the floor and the animation responded to the position of gallery participants. The visual and projection design was gorgeous as was the sound. The animation was a bit rudimentary, but the overall experience was really spectacular. https://oasis.im/en/dreaming-a...
 Looking at that the first thing I think of is how weird the content must look as a video or picture file on a computer. It'd be such a strange resolution and shape. Very cool though!
@jtsteph thans for shearing!
Amazing this inmersive instalation...It would be great to know and learn more about this proceudure (motion tracking on the floor) also about hardware.
It is evident that this is cuting edge and Isadora should be part of this in some how....also with reactiv visuals
What do you think?
Best,

You may find the video scenes in this file of mine helpful in terms of learning how to build crossfades for videos with both video and audio:Â https://troikatronix.com/add-ons/random-media-random-duration/
Also I made a little example file that takes a stab at your use-case. Hopefully you can modify it in such a way that it's useful to you, or dissect it and extract the ideas. If you describe the behavior you need in more detail, I can modify the file for you to make it do what you need: manual-override-for-automatic-cues-2024-02-06-3.2.6.izz
Here's the first Scene at the beginning that has the example I built for you:
The second Scene has five methods for automatic time triggers:
The third Scene has a bunch of my time/time-based User Actors and ones that I've collected from others that might be helpful:

@woland Amazing resource! Thanks SO much... Â - John
Thank you @Woland for your detailed response  !!...and the suggestions to start with something smaller.
big hug,

ps I will surely come back with more questions haha
there are many ways to do this by combining actors. you can stop a mov from playing by triggering a value of 0 to its Speed input.
the Selector actor might be useful. or a system of Video Mixers. or some Gates. Or multiple Projectors that get switched on and off when needed. Trigger Value will be your friend for most of these methods.
