So to sum things up.
On each individual fixture you have:
- Fixture DMX address 001
- Fixture DMX address 013
- Fixture DMX address 025
- Fixture DMX address 037
In Sweetlight you've set:
- Chauvet H6 1-12
- Chauvet H6 13-24
- Chauvet H6 25-36
- Chauvet H6 37-48
And last, in Editor > Steps, you select all 4 fixtures while button DMX-send is Active in
only this window, and
not in Live > Buttons/TimeLine/Sequential list
OR Editor > Generator
(This is for debugging though)
