CMY virtual dimmer question

[Roberto]

Hello guys,

 

We recently obtained some used Showtec Phanton 250 CMY wash heads.

I downloaded the fixture file from the library v.30.

Unfortunately I did not succeed in using it to dim this fixture using our zero88 mambo frog console.

 

So I have created an extra virtual dimmer channel and let it control the CMY colors.

As you will probably know this does not do the trick. In fact this dimmer does not have any influence.

 

So now I gather I might have to control the shutter using the virtual dimmer channel.

However the shutter values are 0-99 for dimming and then strobe like effects up tll 255.

 

Here I am stuck and hope someone can help me with some good ideas.

Thank you in advance.

Hi Roberto,

 

Yes - this fixture doesn't have a dedicated dimmer channel, which makes things hard!

 

You're right that the Virtual Dimmer channel needs to control the shutter value, not the CMY. You then need to change the default of the shutter channel to "86" - which is the dimmer at full.

 

This will work most of the time, just because if you try and fade in / fade out whilst strobing - because what will actually happen is you'll fade through all the different strobe settings / speeds which will look nasty.

 

Unfortunately, it's a limitation of these fixtures which don't provide a dedicated dimmer.

Dear Jon,

 

Thank you so much for your quick reply. I think this service is a very strong point for zero88. I am going to try this setting later today.

 

If you don't mind too much, I will use this topic for a different question on this wash. In the Position group in the desk there appear some movement effects like Ellipse that work straight away on our Macs. But they do nothing for the Phantoms. Is there a reasonable way to make this work?

 

Thanks, regards

In the fixture library, you will see a "special" drop down, allowing you to select a predefined parameter. If you choose "pan" and "tilt" for the pan and tilt channels, this will link the parameters to the effect movements on the Mambo Frog
