Hiya,

I think there is a limit of 16 knobs to control a generic fixture? Is it possible to increase this? Eg when trying to control all the pan and tilt parameters of 16 MH lights in the same tag set I would need 32 knobs for the movement and at least 5 more knobs to control other parameters.

Thanks

Hi @Hungry_Man, that’s indeed the case! A device that will expand the possibilities around this is in the making. In the meantime, I would recommend dividing 16 moving heads into multiple tags.
