[REQ] Delay between fixtures

I have a huge building with 60 white LED (1 channel) and 41 RGB LED (3 channels) but the company that installed everything, has a computer that can't control all the fixtures together at the same time (can't calculate the fixtures all together). When I try, I have a delay from about 1 second. So when I want to fade, I can see difference after 1 second, and the fade is really ugly, because when you want a fade out of 3 seconds, you actually have a fade out of 3 steps in 3 seconds.

But when I control the fixtures one by one, there is no delay.

Now is my question:

I there a fast way to make a scene fade in and out every millisecond 5 fixtures at the time.
So 5 fixtures the first ms then 5 fixtures the second ms ...etc. And every fixture decreases by 10 (I don't know how you call the 255 of a channel)

I don't think there is a fast way, but maybe somebody knows a way. (I can always ask;) )

This is the light I have to control.

If it takes 1sec to update 100 fixtures, it should take 50ms to update 5 fixtures. Doing like you propose will bring the computer to its knees too.

Run QLC+ with an engine tick of 1ms and change the output plugin so it only outputs 5 fixtures at a time. How does QLC+ communicate to this computer?

Also, what's the purpose of this computer? Can you remove it?


EDIT- Is QLC+ running on this computer ? I didn't even ask. Is QLC+ even running anywhere on this setup ?

There is a computer (server) that makes it possible to work with a tablet (browser) and behind the server there is a ethernet controller for the lights. More I don't know about the installation. (They are very secretive about the installation)
When I use the tablet, it have only presets (made by the company Living Projects, Philips). I can't change anything about these presets. That's why I want to control them myself. Everytime I want something changed in the presets, they have to write a line of code to make it work.
The tablet has also a delay of 2 or 3 seconds. But when it is in a chase, it fades nicely.

So now I think my computer's signal goes through the other system which makes a delay. Now they say they can fix it but it will cost another 2.200 euros to use a stronger computer to make the calculations. (So I've been told)

I don't know the exact time of delay, but I am going to time it.
I use my computer with the DMXking Ultra Micro. I can communicate via DMX.

And I know I can't mess with the installation of Living Projects...

I guess this is the installation: http://livingprojects.nl/en/news/home-o ... d-lighting. They mention Philips Color Reach Powercore Compact fixtures, which are driven by this device: http://www.colorkinetics.com/ls/pds/dataenablerpro/ The driver supports ethernet (using some Phillips protocol) and direct DMX. You'd have to find out if you can tap somewhere...
