Q Light Controller+

Hi,
When I add a single device to Qlc it will work fine. When I add a second device it will either not work, or the channels are mixed, and it will affect the channels on the first device. Can anyone tell me whats happening please? I haven't use QLC for a while (I'm only a hobby user), when I last used QLC it was working great. Thank you.

Hugh?
You cannot mix addresses inside QLC+. They are strictly set.
Or you changed the channel mode in your fixtures, or they have a wrong start address.
If a second device is added on the DMX bus and by doing so the first one is affected, the 2nd fixture is set as 'master' and the other one is a slave?

Try adding 1 fixture and verify. Now detach the 1st and add the 2nd. Verify working state. Now add the 1st one again with the 2nd also connected. If they react strangely, verify slave mode settings on the fixtures...

i forgot to mention that the devices I am adding are different. One is a laser the other is a Derby light. Which ever way I add them the second device doesn't work and interferes with the first. Any help please?
