Hello Robrolefes,
If I have understood you correctly you want to control more then 64 fixtures with Cuety. Or 64 fixtures with sub-fixtures. Like an LED strip where the strip as a whole would be considered to be a single fixture.
Cuety does not manage sub-fixtures and can not manage more then 64 fixtures. If you want to control more then 64 fixtures, Cuety can not control every fixture / led. If you are able to find an LED strip which has preprogrammed effects, you may be able to "control" more fixtures. But this will limit you to the preprogrammed effects of your LED strip which Cuety can not change.
You can use preprogrammed effects. However your LED strip will decide what will happen. And sorry I do not have a list of fixtures / LED strips which have these preprogrammed effects.
However we do have other products which can support more fixtues. If you want to use more fixtures and or sub-fixtures you can use a CueCore2 or QuadCore together with CueluxPro.
Best regards,
Guido
