Well, you CAN do this, but you've got to create scenes that cover every possible scenario you'd want, and then have a chart documenting what's on for which scene. But on the go, that might be too much to deal with, as its too easy to overlook something.
I'd say MyDMX by American DJ might be an option with or without a MIDI controller. It's a PC based software solution. While you can also make scenes you can name, you can also override the scenes using HTP or LTP to determine priorities. It's not much more than the DMX Operator.
While I haven't seen these yet, there are other Elation software offerings available I hear Compu Live by Elation might be a good option Maybe Compu Cue. I haven't used either. I could definately see Compu Show being used, but I think that would be too much money
Another alternative might be this older switching system ADJ used to make. Maybe I'm wrong, maybe they still make it. It was basically a remote controlled outlet bank that connected to a switch panel that let you turn on/off the power plugs.
Now, if you want to do things like color sync your roller trons(forgive me, I don't know nor care what they are and am not taking the time to enlighten myself on them), and I take i they are a DMX fixture that can work in master/slave mode, then if you expect color sync, you have TWO options:
1: Don't run them in DMX mode, run them in master/slave mode. This guarantees they work together in sync.
2: If thhey are DMX fixtures, and let's say they support sound active in DMX mode(some fixtrures don't do this), then there's now way to get them to sync up, so you'd probably need to go software to control them in sync, and not use sound active mode.
You could add power packs and dimmers as needed and where applicable and direct DMX control where you want it.
I think you got too much stuff and want too many fast options based on your needs and the controller you have. you still have options. For the most part, if you address things right, and use POWER packs or dimmer packs in SWITCHED mode(not dimming), such as the current DMX-DP20L's(made by Elation), you COULD do this. Plug everything into the packs, use the faders to bring stuff UP and DOWN. The only possibly downside is that you may need to use the shift button to get to other channels.
Keep this in mind. the DMX Operator supports 192 DMX channels. The scanner buttons access logical channels in groups of 16 consecutive channels. If you hit Scanner button 1, you have direct acces to channels 1-8 via the faders and when you hit shift you get channels 9-16. If you hit scanner 2, you get channels 17-32(and repeat). BUT, if you hit Scanner buttons 1 and 2(and more), Fader 1 will be bother channels 1 and 17(and maybe something else).
So, now my question is, do you have any dimmer and/or switcher packs? You're going to need some. Some of your fixtures are DMX, so you don't need to get these packs, but since you seem to want simple on/off operation, you might need to get enough anyways.
The dimmer packs support 2 outlets per channel, but you can you other stuff to get more plugs if you need to(say, a power strip). But, in general, this sounds like it would work for you, since I don't see you needing more than 2 lights on the same channel.
But, this is a hard one. You need to buy more stuff for sure, and if you don't need to buy dimmers for DMX fixtures, it might save you money, which could be used to get lighting software(MyDMX) and an inexpensive MIDI controller like the KORG nanokonrol.
So, you're ging to need to look at your options and bank account and decide what to do next.
