Help with using ArtNet to Deskontroller to LEDStrips

Beginners
1

I’m trying to control 8 Addressable RGB LEDstrips using Artnet with a Deskcontroller Lite
Deskontroller

I followed this nice tutorial

and I can control one led strip at a time

I was able to crop a TOP into 8 single lines, and then use the same method to have a CHOP that represents an LED RGB strip.

Now I think I need to combine all the CHOPs into a single one, each one with its own name, but I’m stuck now.

Any help will be much appreciated.

Each LEDstrip has 140 RGB pixels.
The DMX Address is as following:
1st strip:
Universe 1 - R
Universe 2 - G
Universe 3 - B

2nd Strip:
Universe 4 - R
Universe 5 - G
Universe 6 - B

3rd Strip
Universe 7 - R
Universe 8 - G
Universe 9 - B

and so on…

Your 8 single lines have waaaay more than 140 pixels in them so you need to get that down to 140 pixels first - use a resolution TOP or something to get the size down. Then you can use a single TOPto CHOP to translate the TOP to CHOP data and then use Shuffle CHOPs to split or combine all of the samples.

You want to create a CHOP that has multiple channels in it where each channel is less than 512 samples since DMX is split into “universes” of 512 values where each “value” could be the R, G or B of a pixel - AKA 3 “values” make up one “pixel”. (btw I think you are mixing up “unviverse” and “address” in your post… unless the LED strips really are expecting to get all of their red values at once on a single universe. I’ve never seen that before.)

You could use a merge CHOP with your current setup but having so many TOPto CHOPs is not the most efficient way to do this, so I would recommend figuring it out with only a single TOPto CHOP which you are close to at the bottom of the file - just use Shuffle CHOPs to split that one channel into multiple shorter channels.

Hello Peeet! Thanks so much for taking the time to help me with this.
There’s a lot of information on your post to digest.

Regarding the DMX address / universe, the person that gave me the Deskontroller Interface told me that the LEDs mapping was configured this way, one DMX universe per strip/color. That’s the reason I’m approaching this TD patch this way.

On the other hand I still haven’t completely understood how the data manipulation in TD works, I understand that the Shuffle operator splits data in many ways, but I don’t understand how to make it work the way I need.

Other that that, I’m going to watch the tutorial video again to see if I missed anything, and to see if I this things make more sense to me.

EDIT
One thing I forgot to mention, right now I’m using Madmapper between TD and Deskontroller. I’m sending video to MadMapper using Spout and everything works ok. I just would like to remove Madmapper away from this setup, and of course, learn more about using TD with Artnet.

2nd EDIT
And you’re right, I’m mixing Universes and Channels… :joy:

I managed to make it work, probably not the most CPU efficient but it works! :star_struck:
Thanks so much for the enlightenment!
