Hello,
like in the grandMA1 and grandMA2 there is a HTP Merge in the grandMA3. Edit Universe x, Merge Mode "HTP".
The temp faders also work like in the other software series. The temp faders only work from 0% to 100%. All fixture colour mixing channels, whether CMY or RGB, must control from 0% to 100%.
You save a cue with all RGBWACMY and the dimmer attributes at 0% and switch it on.
Then you save a single colour attribute to a single temp fader.
You assign the temp faders to DMX addresses in the in&out/DMX Remote menu.
The HTP value from the external desk can then control the dimmer.
The external console parks all colour attributes to DMX 0% then the grandMA3 can adjust the colour attributes with the temp faders.
