Hello, my SPS-121 LED spots flicker unintentionally at irregular intervals, but only in 7 channel mode. If I change the output frequency the flickering speed changes.
I control it with QLC+ 4.12.7-1. It doesn't work with QLC+ 5.00.0-0 either.
I use Windows 11.
I use the Enttec Open DMX USB interface.
Can anyone help me.

Sure, you said that in your first post, but that isn't an answer to the question...
channel 7 is a mode selector and channel 6 acts as a strobe speed or effect speed setter, depending on what 7 is set to.
I assume Kenact wanted to see how you set these up when your flicker appears, to exclude user error.

This indicates that the DMX interface(s) is/are working OK. They don't care which mode your fixture is set to, they're just sending values on DMX channels...This problem does not occur in 4 channel mode.
Can you share and attach your fixture definition and possibly the workspace you use with it, here?

In your Fixture definition you defined channel 7 Effekte as "Intensity", instead of "Effect".
A QLC Workspace is like a Bob Ross painting: "it's your world, you can create whatever you want!"

Did you restart QLC?

Just to summarize and make sure I understand correctly:
Using this workspace and fixture file, only the Showlite SPS-121 (not any of the other lamps), and only when set to 7 channel mode, exhibit this random flicker?
I don't know very well about electrical properties of DMX, transmission frequencies and all that, but if that's true, in my mind this strongly points at the fixture behaving badly.
Apart from that I'm out of ideas currently.

I had some time to dig in,
In your project, you use them as a 4 channel fixture,
The fixture profile uses channel 7 as intensity <- bad
What is the make and model of the pixel-bar? If it's Chinese, I had some bad experiences with some behaving as a DMX master (sender) and destroying the DMX signals...
A current status, please?

All electric machines work on smoke... when the smoke escapes... they don't work anymore
