Brightness parameter in Submaster acting like LTP

[LeeStoddart]

Strange thing today on Illusion 500 with version 1.7 software. I wanted to setup a submaster which had the BRIGHTNESS channel for my 4 MAC500 fixtures.

 

I selected the four fixtures (Group 14) set the brightness to 100% then did Save As a submaster (2.1)

 

Reset the brighness to 0 in the Program Window. When I raise the submaster fader to 100% the four fixtures come on but when I lower the fader to 0% the output remains at Full????

 

Are they behaving like the Brightness is an LTP parameter?

Brightness parameters are processed HTP - therefore check that there is not another source which is causing the fixture brightness channels to be output at full. This could be from the Program Window, Current memory on the playback x or another submaster.
