Hi everyone, My friends and I are currently developing an open-source lighting control software and we want to add complete GDTF support. Because of this, I am currently working on deeply understanding the GDTF specification so we can implement all its features correctly. I have already created some GDTF files that work flawlessly on grandMA3, utilizing almost every feature I've discovered in the GDTF Builder. However, I still don't fully grasp the exact purpose of Logical Channels and why I would need to use multiple Logical Channels on a single DMX-Channel, instead of just using multiple Channel Functions within Mode Master Containers. I've created some test GDTFs trying to use two Logical Channels on one DMX-Channel, but I can never get them to work—they always show up as red (invalid) in the Builder. I searched the GDTF Share for examples of fixtures that actually do this in practice, but I couldn't find a single one. Does anyone know of a specific fixture on the Share that successfully uses multiple Logical Channels? I would love to look at a working example so I can finally understand their exact use case. Thanks!
