When I am in EDIT mode and
- select the scene "Beam ON" the moving heads light up as planed
- When I than select the scene "Blue" the color wheel changes to blue but the moving heads go off as the scene "Beam ON" is automatically deselected.
That's normal so far because, in Edit mode, only the current scene is "loaded" for making changes.In EDIT = one scene at the time
(except for fade parameters, etc. but not for channels themselves).
The same happens in LIVE mode.
I've tested your show file on Windows 10 with the latest Daslight4 version (Jan 13 2020) and it works fine in Live
Check this : when the 2 scenes are running together (Beam + Color), a manual operation on the faders overrides the programmed data in the scenes. In that case, the "ON" indicator turns to LTP or HTP. The "Reset" button clears the manual values, so the "pure" scenes data are played again.
I don't know if this is an issue due to Mac only, it would be strange.
Let me know if you've found what's wrong meanwhile.
Hope that helps.
