Create fixture for a 4 groups 12 channels led decoder

Hi. How to create a fixture for a 12 channels 4 groups dmx led decoder? Is the a preset that I could use to start with? Thank you!

Hi !
What is the manufacturer and model of your decoder ?
You can create your own fixture and we can help you if you want.
If there is separately channels for each groups you can create a small fixture (3 channels) and patch it 4 times.
Otherwise you can create a 12 channels fixture ton control all of your 4 groups with only one. (I prefer the first one for uncoupling)
