Thanks for pointing that out. Lately, many consoles now have some kind of Virtual Dimmer channel function (usually defined in the patch or fixture personality) that behaves in the way you describe – acting as a “master” for all LED colour channels.

This “dimmer” is also pretty useful when pixel mapping, using a black and white map for opacity. How it works varies from desk to desk, though. It’s something we will probably cover in the not too distant future.

Thanks for your comment.

About the description on channel 9… I just thought I’d say, that controlling some of these LED fixtures, which don’t have a separate master dimming level for reds, greens and blues, was quite easy with Chamsys’ multiply function in the patch window. That way you could create a “ghost” dimmer channel which acts as a master for the three real color level channels.

Doing this made it possible to adjust dimming separately and using colors eg. from the palettes easily.

Nothing special,

just found this blog of yours today and it’s lots of good stuff!

The new generation of RGBA LED fixtures do create a much nicer white. Some LED’s at PLASA had improved output too. I am sure all these issues will be ironed out including LED deterioration. Currently the older some LEDs are, the bigger variation in colour temperatures.
