I have to say i dissagree. Dimmerpacks, or a similar model is highly necessary. I am running 4 zero 88 dimmers (which are 6 channels, and 12 sockets (2 per channel)) and you cannot (without massive difficulty) add 2 fixtures to the same channel. Like wise if i wanted to address 4 LED cans to the same address (to speed things up), I can't do this either. Now i know there is a way of doing this on the patch screen in the 3DV, but it doesn't relate to the set-up screen and becomes untidy and confusing. So please give us some way of adding Fixtures to the same channel.
Other than that a great product for great money.
