Thank you Petr. We have updated our GDTF files to include a default value for each channel function.

Hi, what is the correct use of channel functions, for example in relation to fixture Internal FX Macro's? What I have done so far is create different channel functions for different types of effects. For example: DMX 0-50 Intensity FX (and then insert channel sets for the different effects in that category) DMX 51-100 Colour FX (and then insert channel sets for the different effects in that category) DMX 101-255 Complete FX (and then insert channel sets for the different effects in that category) This seemed to work fine, as MA3 was generating different "tabs" for the different effect types. But now with the updated builder, my files give an error, as the Default DMX is the same for the 3 channel functions? Check out Martin -> VDO Fatron 20 1000mm for example. Best Regards, Wouter
