Hi,

    I'm probably over thinking this, but is possible on the Element to mix conventionals, on a cyc for example where you patch each dimmer to the correct color, for example dimmer 1=blue D 64 =red, and D 4= green?  I have RBG conventional Sky CYCs and I was thinking that I might be able to mimic this using an RBG LED profile, if,  the dimmers are in order, aka 1,2,3 but, only if they are plugged in the same order that the LED fixtures use. But I wondered if such a profile exists

 I suspect the response will be " you can't do that because the board doesn't know what gels are in the lights" But, I'm not really looking for pin point accuracy, rather the proportional dimming possibly a mildly acurrate color response from the picker. I'm thinking profiles for RGB, RGBW and maybe RGBA conventionals for CYCs. 

Does it already exist or is it not feasible? thoughts?

Hi Craig-

You could certainly patch this using Red, Green, and Blue from the manufacturer called "Custom".

The problem that you'll run into is that the software puts a virtual intensity into RGB LED fixtures - this would not be the case with the method above. As such, you could control the RGB lights with the Color controls, but you wouldn't be able to proportionally control the intensities.

Hope that helps-

Hi Craig -

Luke is correct and this actually works pretty well. You do need to "forget" that the fixtures are individual dimmers though and just let the color controls do the work. I'm not entirely sure what Luke means by losing individual intensity control though, as you would simply adjust the individual colors down or up, which would essentially be controlling the individual intensities. The main intensity channel would become a master for all three colors together, so perhaps that's what Luke's getting at. :-) The cool thing about that is that the intensity of the RGB channel deals with fading the color in a true fashion - meaning it will scale the individual colors (as much as it can with dimmers - the lamps themselves will introduce color shift that the console knows nothing about) so that the color stays as true as possible during the fade. Give it a try and see if you like it!

(And yes, the dimmers do need to be in order for this to work - typically 1=Red, 2=Green, 3=Blue for one set of cyc fixtures to equal one RGB fixture. The next set of cycs don't have to start at dimmer 4, but whatever three dimmers they use should be in numerical order for R, G and B.)

Thanks-

Hi, i read this and it sounded very interesting to me.

We just ordered an Element (today, in fact). Am I interpreting this correctly in that I can set up my Cyc lights as one fixture in the Element and have it treat is like a single RGB fixture? Would I be able to use the gel picking feature with this? I understand that the colors would probably not be as accurate as LEDs, but that's fine with me.

 

Thanks, Jacy

What happens if you assign each color to its own part and use the fixture types "Red 6B" "Green 6B" and "Blue 6B"? I just tried this in offline, but like was mentioned above, there was no "dummy" intensity channel. I also couldn't get the color picker to affect the color values. I tried adding another hue and saturation as other parts of the channel, but changing the hue and saturation did not change the RGB values. Are the custom fixture types meant to be put into parts like this, or are they for something else?

AJBlank - You should use the "Generic" > "LED RGB" fixture type as suggested by Sarah. (There is also RGBA etc)

These work 'out of the box' with built-in virtual intensity. If your cyc dimmers are in a different order, you can clone these types and rearrange the RGB into the correct order.

Keep on trying till you run out of cake.

Okay, but what are those custom fixture types for?
