Q Light Controller+

Here is a full featured fixture for the Stairville Infinite Pixel 250, the only thing that I didn't do is the physical things.
This fixture can work in 8, 18, 108 channel mode, I created the fixture for each channel mode.

If you don't include the physicals, it won't be seen in the 2D monitor...

Looking at the defintion - it is unacceptable ... you did forget to add the heads (in 108ch mode there are 25 of them)
