Sorry .. but I disagree ..

If I add the RGB Fixture .. it only send out 3 DMX Channels (this is confirmed by your own DMX monitor) ..

I need 4 ..

I have

-Control
-Red
-Green
-Blue
Your fixture is not a generic RGB device. For that reason, it needs a personality to work correct. Of course another personality with 1 channel (dimmer for example) + RGB will work. But I"ll be happy to create one for your specific manufacturer/fixture if you explain what the control channel does (is it just dimmer, or is there also strobe on the channel?).

My post was about the colour mix that works how it should: RGB get's mixed HTP even if it's spreaded over a couple of playbacks.

Thanks ..

It's a Lite Emotion RGB64LED

CH1 is Dimmer and Strobe
CH2 - Red
CH3 - Green
CH4 - Blue

Ch1 is dimmer to 50ish% then various strobes above that .. then FL again at 100% ..

CH2-4 is just Dimmer (Slaved from the CH1 Dimmer/Strobe)

Hi Jeroen,

That's just a matter of requesting the personality file including the correct control channel. If you give me details of the control channel, the name of the fixture and the manufacturer, I'll be able to add it to the library.

RGB manual control via 3 faders works just fine here with any LED-fixture:

- Select fixture, dimmer to 100%, RECORD to playback 1
- Clear programmer (click CLEAR twice to make sure it's empty)
- COLOUR page > RED to 100%. Record to playback 2. Red back to 0%.
- COLOUR page > GREEN to 100%. Record to playback 3. green back to 0%.
- COLOUR page > BLUE to 100%. Record to playback 4.
CLEAR programmer.

Start playback 1, 2, 3 and 4. Use fader 1 for dimmer control, use fader 2 for RED, fader 3 for GREEN and fader 4 for BLUE.

Works like it should: Colours mix in realtime (HTP) controllable by the faders..

OK, it works, but I have to "waste 3 faders" to set up 2 scenes :(

So why don't you make 1 cuelist with several cues - each cue is one "scene" with one color? That's exactly what cues in a cuelist are for.

I agree with you, but you can only work with cues if you know what comes next...  ;)
In the shows I'm doing, I often have to improvise. What's easier, pulling down one fader and pushing up an other, or searching the right cue?  ;D

Jeroen .. I was wrong ..

I'd only done my tests by looking at the DMX output ..

The fixture I mentioned will work fine for my LED's .. but i thought my control was on 1 .. it's on 4 ..

Can you write a version of the fixture Visual Productions>Canvix Master - with the dimmer/control on CH4 instead of CH1 making 1/2/3 as R/G/B ..

Is that hard to do? ..
