Patch Editor and DVI Patch are about one and the same tool. The term DVI Patch specifically refers to working with DVI fixtures.
On the one hand, working with DMX-based fixtures is relatively easy and can be managed with the help of the Patch Editor without much difficulty. You can simply add fixtures, rotate them, or add space between fixtures, for example. Without the DVI Patch, on the other hand, it would not be possible to add rotation or spacing to DVI-based fixtures, because of how DVI hardware controllers work.
The DVI Patch allows you to add
to your LED installations with DVI fixtures.
The DVI Patch can be used when working with DVI fixtures and the following output methods:
DVI controllers receive a signal [input] and map it to the LED fixtures [output]. But due to their construction, DVI controllers usually need to receive the input images in a linear way, in one whole block of information [often like a rectangle] — no matter how the actual LED installation looks like.
In other words, when your LED installation looks like this for example:
Then, your DVI controller will probably need the input signal to look like this:
This is no problem for MADRIX. It will transform the signal for your DVI controller according to your Patch configuration.
While the DVI fixtures represent your LED installation in MADRIX and its Previews, you can customize their DVI Mapping settings for the controller that receives the signal. As shown above, DVI fixture settings and their DVI Mapping often are two different things if you add rotation, flipping, or spacing. That is why you will have to configure the normal DVI fixture settings and their DVI Mapping settings separately.
The Patch Editor provides three view modes. Regarding the DVI Patch, the DVI Map is of special importance, since makes it possible to configure the required DVI Mapping of the DVI fixtures.
In order to work with DVI fixtures, follow the instructions below:
1] Position your DVI fixtures in the graphical workspace of the Patch Editor according to your LED installation [using the view mode Voxel Map].
2] Set up the size of your virtual LED matrix [using the Matrix Settings]. Normally, the area it defines should include all of your DVI fixtures.
3] Activate the view mode DVI Map [Keyboard shortcut: F6] in the Patch Editor.
4] Adjust the DVI Mapping of every single DVI fixture according to the requirements of your DVI hardware controller. [The DVI Mapping of the first DVI fixture normally starts at position X:1, Y:1.]
Step 3, 4, and 5 are only necessary, if you wish to add spacing, rotation, or flipping to your Patch that includes DVI fixtures.
The DVI Mapping of DVI fixtures represents the fixture configuration for the DVI hardware controller. DVI Mapping settings can include their own position, rotation, and flipping settings. In order to work with DVI Mapping, you need to activate the DVI Map of the Patch Editor.
You only need DVI Mapping if you are using DVI fixtures in a different way than what the DVI controller expects.

How To Configure Two Rotated EUROLITE LSD 37.5
The normal setup of two EUROLITE LSD 37.5 fixtures looks like this [schematic]:
In this example, we will configure the two fixtures to be installed like this [schematic; without space]:
Step 1] Adding DVI Fixtures
1] Create a new Patch. Go to the menu File > New Patch [Keyboard shortcut: Ctrl+N].
2] Add the two fixtures. Go to the menu Edit > Add Fixtures... [Keyboard shortcut: Ins]. Make sure not to select Merge Fixtures
3] The Patch will look like this:
4] We need to rotate both fixtures to match the LED installation. The left fixture is rotated by 90°. The right fixture is rotated by 270°.
[If you receive an error message about the fixtures being out of range, move your fixture towards a free location on your workspace. Then, rotate them and move them back.]
Step 2] DVI Map
5] Switch to the DVI Map. Select View > DVI Map
Step 3] DVI Mapping
6] Deactivate Link
7] Select the first DVI fixture with its DVI Mapping and position it in the center of your workspace. In the section DVI Mapping, change Rotation to Original and click OK
8] Select the second DVI fixture with its DVI Mapping and position it in the center of your workspace. In the section DVI Mapping, change Rotation to Original and click OK
9] Arrange both DVI fixtures with their DVI Mapping next to each other in the upper left corner. The DVI Mapping of DVI fixture 1 is positioned at Position X: 1, Position Y: 1, Position Z: 1. The DVI Mapping of DVI fixture 2 is located at Position X: 33, Position Y: 1, Position Z: 1.
10] Switch back to the Voxel Map. Select View > Voxel Map [Keyboard shortcut: F5].
Step 4] Matrix Settings
11] Go to the menu Edit > Matrix Settings.... Enter Size X: 128, Size Y: 32, Size Z: 1, and Color Depth: 3. The virtual LED matrix now matches the size of both fixtures in total.
Step 5] Result
12] Your final Patch should look like this:
12] The DVI fixtures and therefore the 3 Previews will represent your LED installation:
Please make sure to save your MADRIX Setup file after the configuration process.
You may also save and/or export the Patch as a separate file [of the file type *.mpz or *.mpx].
