Apollo or Wybron are both good brands. You will see colors scroll past in front if you are doing a dance chase, and that will also wear out the gel string faster by whipping it back and forth really fast. But, if you set your string up so that throughout the chase you are just moving from one frame to the next, you'll be good there. Just line up your chase (20 or fewer frames max), and then you can have it move from one gel in the scroll to the next. If you're doing dance chases and can't do this, go with some sort of RGB type fixture/3 fixtures.
And if your focus is broader than color scrollers, there are tons of different kinds of fading/mixing scrollers with two gel strings of cyan/yellow and cyan/magenta, RGB mixing fixtures, LED fixtures, and all of those kinds of things.
Well there is the High End Color Command... The SeaChanger...
Try and stay away from scollers especially if you are going to fly through the colors to try and attempt to re create a moving light chase. If your going to go from one color to the next over time then it's ok but noisy.
I really like the Color Commands... only 4 channels and full CMY color mixing. Practicly a 750w Par. Not a bad item.
the Sea Changers from what I hear are amazing but are expensive for what they do.
The color commands also change colors REALLY SLOWLY.
Well, OK, really slowly is an exaggeration, but I tried to do a quick change with one, and it failed miserably. They are wonderful for most other things, beautiful colors, beautiful changes, but if you want snap color changes, not gonna happen. (The Color Merge, on the other hand, does nice snap changes though.)
Really, there is no good way to do the snap changes your talking about with any changer/scroller type thing. Anything I can think of will require more time then you want to move the glass/gel scroll to the next color.
I would say either
a) get lots of Source4s (or whatever) with all the colors you want and hang them
b) rent a moving light with a color wheel. Color wheel should do some fairly quick snaps (though, of course, depends on make/model)
c) get 2 sets of Source4s (or whatever) with scrollers/changers. system a turns on with color 1, system b scrolls to color 2. system a turns off while system b turns on. system a scrolls to color 3........ and so on and so on.
Of course, all of these require decent budget.
Oh, choice d would be to hang a red, green and blue light and color mix with those. Won't work perfectly, but always an option.
Looks like it might be wiser just to use gel permanently and specials.
By the looks of this, colour scrollers are expensive for what they do (if they do it well).
Does anybody have any ideas for some other effective implementations of DMX for glitz/other? We have permanent DMX moving light control, but we only hire in movers when we need them so it would be really great to have something on hand all the time to use and to train people with.
Thanks again - sorry for late reply, I have been away from home.
If you want a simple ML trainer that is also functional the S4 revolution with a shutter and gobo package is a nice moving special with a color scroller but also repositional. It has its limitations, which have been discussed numerous times, but I think it is a good model to use for people who are not used to MLs.
I was surprised to see the Color Command is still available. I figured HES would have dropped that when the Studio Command was released. My opinion of that product is different than some (don't like it), especially since the Studio Commands are available, but that's irrelevant. You have to go with what is available, what works best for you, etc.
You might also look at the ColorPro HXi from High End, if there any available in your area.
Color scrollers save alot of circuits if you just want to change frontlight colors between dance pieces. They allow amazing design flexibility, but just aren't all that great for smashing through colors during a show.
Hmmm...the Revolution seems like a very expensive package just to be an ML trainer in a school. For purely training purposes (not to show of crazy ML skill during a show), just get something by a DJ company that takes an ELC bulb. This is a 250W halogenbulb that is sold in bulb lives up to 1000 hrs. I think that chauvet makes an ELC moving head (Mini Legend ILS) that goes for around $500, and Optima Lighting actually makes some decent ELC scanners (Mojo IIX and IIIX) for about $200 that is a better model among their series. Keep in mind that these probably won't have the precision or the punch of a regular moving light, but they will be able to be used in demonstrations. The IIIX has rotating gobos, but it doesn't have many of them. I'm actually thinking of getting a IIX or IIIX for myself for when I have to do "DMX basic training" this spring at my old high school.
EDIT: Just adding reasoning here - the reason that I said to get an ELC bulb is that it is a halogen lamp, not an arc lamp. This means that you don't have to kill bulb life every time you turn it on or off. Yes, I know that the S4 revolution can take a standard lamp, but it's rather expensive for some high schools. There is a gigantic difference between $3.4K and $0.2K. And then, if you want any other functionality, you have to get modules.Iris, Shutter, Gobo, Rotating gobo, whatever you need. And then you can only put 2 modules in.
