MADRIX Version: 3.3 (Created with)

Note: It is important for this tutorial that the screen-capture software of your fixture is installed and working correclty. If you use the software LED Studio, this tutorial can be very useful to you.
In this example, we want to control 16 EUROLITE LED Pixel Mesh 64x64. The fixtures will be installed in a 4 by 4 grid. We will use the screen-capture software LED Studio 10.4D in this example.



Configure your screen-capture software.


Start MADRIX and go to Preferences > Patch Editor or press the F3 key.
(If you do not know how the Patch window works, please have a look to this »Creating A Patch With Different Fixtures)
In the Patch Editor, click the New button on the toolbar. Afterwards, click Add and change the following settings in the Add Fixtures window:

Protocol: DVI
Fixture: EUROLITE Pixel Mesh 64x64 16x16 pixel dvi
Count: Set X to 4, Y to 4, and Z to 1
Merge Fixtures: Should be Disabled (the checkbox is gray).
Start Corner: Bottom Left
Main Orientation: Vertical
Snake Mode: Should be Disabled
Start Position: Leave the default settings (X is 1, Y is 1, and Z is 1).

Click OK


We need to change the Matrix Size to 64 x 64. Click Matrix Size on the toolbar and set Size X to 64, Size Y to 64, and Size Z to 1. This step is necessary because the Patch Size is not be updated after changing a patch and its included fixtures.

Click OK


Close the Patch Editor.


Go to Previews > External Preview 1 and select DVI

Now, you can see a (small) new window according to the size of your patch. In this example, its size is only 64x64 pixels.


Start your screen-capture software. It is important that the External DVI Preview Window of MADRIX is positioned in the capture area of your screen-capture software. Perform a left mouse button click on the External DVI Preview Window of MADRIX and move it to the position of the capture area while continuing to holding down the mouse button. Or go to Previews > External Preview 1 > External Preview Settings.... The External Preview Settings window will be opened. You can adjust specific settings there:

DVI Window Position: Here you can set the position of the DVI Preview Window starting from the left and from the top.
DVI Windows Size: If Display Area Size is enabled, the size of the DVI Preview Window is as large as the Patch Size in pixels. If it is disabled, you can change the Width and Height of the DVI Preview Window.
Display Area: If Full Size is enabled, the complete patch size will be displayed on the DVI Preview Window. If Full Size is disabled, you can choose which area (from which and to which pixel) should be displayed on the DVI Preview Window.
Slice Alignment: This option is important when you have created a 3D patch. Because DVI controllers usually do not accept any 3D input image. So you have to send a 2D image. You can change the Slice Type and the Slice Order.
Display Transformation: You can Flip and Rotate the "DVI Preview Window". That is important if you have turned your fixtures during installation, for example.


Now, go to Previews > External Preview 1 and select Always On Top. Often, this is necessary so that no other windows overlay the DVI Preview Window.


Note: The EUROLITE LED Pixel Mesh 64x64 fixtures we used in the above example are connected as shown in the following picture:


Congratulations! You have set up a MADRIX DVI Preview Window for your screen-capture software.
