Thanks for letting me know. I see the same information as you show above – the R channel affects the first channel of DMX data that is streamed, G is the second channel, B is the third, and W the 4th. Unfortunately, the color that actually appears on the LEDs is different than the color being output, and it only matches the intended color when I swap the R and G values. In the attached image, I’m outputting 255 for the R channel, which looks correct, only the LED strip lights up green.
It seems like this is an issue on the hardware side. We are in touch with some collaborators who have seen the same issue using different software with our particular LED strips and controllers, and they think the channel order on the LED chips might actually be GRBW rather than RGBW. I will let you know if I learn anything more about this, we’re doing some more testing later this week.
Perhaps this is a feature request for the next version – it would be helpful to be able to globally swap the channels for the whole system, in case of strange things on the hardware side. Maybe there could be a “GRBW” option in the Pixel Type for eDMX fixtures? Or maybe there’s an option added to the “Overrides” section of the Art-Net node options in the Devices window that allows you to switch the channel order.
Thanks as always for being so responsive!
