Aura LED TEK Matrix - HELP!!!!

farlander762 · Mon Jan 13, 2020 1:44 am

I have a knack for finding obscure, obsolete, stupid, fun, DJ fixtures in the $20 - 30 range. I work with the youth group at church so they love stupid fun (that's not a criticism, these goofy fixtures do goofy things). This one is a real doozy. It can operate in 2ch, 3ch, and 256ch modes. 2ch is useless, just a 9 pixel dot that can be moved with ch 1 and strobed with ch 2. 3ch is about what you expect, silly patterns. 265ch makes this thing a 16 x 16 matrix. I did find some catalog info on it so was able to input the power, beam angles, dimensions, etc.

I have no manual for it but here is a YouTube video that explains it, the video is 14 minutes long and in Spanish but does illustrate what this gizmo can do. Skip the boring Obey 70 parts...the 3ch patterns start around the 6:45 mark. At 8:14 he punches it into 256ch mode. At the 11:00 mark, he sets up the matrix (Freestyler).

In 256ch mode values 0 - 49 are pixel off and 50 - 255 are pixel on. I have begun building a Fixture definition for it that seems like it will work for RGB matrices. Am I doing it right? Am I really going to have to input 256 heads manually in reverse order per row(16, 15, 14.....3, 2, 1)? I input 4 heads just to make sure the RGB matrix function would accept it; it did. The only reason it's worth the trouble is because it can display text.

I did experiment with making each pixel its own fixture and assigning them to a fixture group. It worked, I did have to flip each "row" to make it number right to left. Someone please let me know if there's an easier way.

Hello

I am not sure whether you have found a solution to your problem but I believe you were basically going about it the correct way.

You can add Matrices to QLC+ but each pixel can be 3 or 4 lets (RGB or RGBW etc) and I don't think your light operates like that. I did think that maybe you could add a matrix that was RGBW and make it 4 by 4 and that would give you 256 LEDS all addressed they way you want but then it might be difficult to program them the way you want.

If you continue on your original path, you can reduce the time to set up you files but editing them directly in a text editor. They are just xml files and if you are careful (make backups) and follow the file structure it is much quicker to do repetitive tasks. I am not sure what your computer experience but some simple text formulas in excel or similar can be very useful.

EG.
In the fixture definition under the head section you will see this code

Code: Select all

<Head>
   <Channel>0</Channel>
  </Head>
  <Head>
   <Channel>1</Channel>
  </Head>
  <Head>
   <Channel>2</Channel>
  </Head>
  <Head>
   <Channel>3</Channel>
  </Head>
  <Head>
   <Channel>4</Channel>
  </Head>

You can just add a extra lines to make up the rest.

Similarly your show file could be edited to reorganise the group you need to create for the matrix..
Just create the group (16 by 16) using the fixture and then adjust the X and Y values or Head values

Code: Select all

<FixtureGroup ID="0">
   <Name>Matrix</Name>
   <Size X="16" Y="16"/>
   <Head X="0" Y="0" Fixture="0">0</Head>
   <Head X="1" Y="0" Fixture="0">1</Head>
   <Head X="2" Y="0" Fixture="0">2</Head>
