Very quick reply on this - thanks Lars.
(onPC steps)
1. Copy the XML file to C:\ProgramData\MA Lighting Technologies\grandma\gma2_V_x.x.x\fixture_layers
2. cd EditSetup
3. cd Layers
4. import *file name* at 1
5. cd /
the console will take captures channel number as the console fixture number..
it works very nicely.
