It seems that masking while recording or merging palettes doesn't work when the palette allready contains data on a Hog4 PC. I've tried different ways to do it, using the command line and the record options toolbar.
I think he is running into a palette type problem (Global vs. Per Type vs Per FIxture).
If a whole bunch of different fixtures are being selected and recorded the palette is probably being recorded "Per Fixture" or possibly "Per Type".
If the Strobe information in the palette is made "Global" it should fix his issue. (you can have any combination of Global, Per Type, or Per Fixture information in the same palette).
