Q Light Controller+

Hello, I am new here. A bit of an intro for myself.
I have been looking at qlc for the last month, working around with it to make sure it was foolproof, and the program is.
I've been interfacing Reaper with QLC+ by way of LoopBe.

The problem is this, I have a bit of a random flickering issue. When I start a fading sequence in reaper, the light I am debugging on flickers randomly. So it will be working perfectly, fading in, looking good, and then BAM, a dropped frame. It's like someone takes the intensity slider and slams it to 0 and quickly replaces it.

I have been looking everywhere to try and fix this, I was unable to figure out how to change the default Hz that QLC sends info at, and I am unable to change the Enttec DMX Pro Mk2 frequency.

Thank you for your help, this community is awesome!

Hi, glad you like the program.

Could you tell us what OS you are using and what version of QLC+ you are running. Possibly your show file.

Quick question, do you have a terminator on the end of your DMX line?

Thanks for the reply!
I am running windows 10 x64. The latest version of QLC+, 4.9.1.
And I do have a terminator at the end of my line.

I attempted to add on a second LED light. So far, I have a THINPar64 and an LED light decoder.
When I run both of these guys through, both of them flicker like mentioned before. It's very random, and probably not very noticeable, but noticed by me

Attached is a picture of the MIDI sent from Reaper. You can see there are no gaps. It isn't exact, the flicker happens randomly it seems. The weird thing is, when I run 2 faders at the same time, they flicker differently. The THINPar64 may flicker, but the LED light decoder doesn't, and vice versa.
Also, when I manually adjust the sliders in QLC+, they don't seem to flicker at all.

If you open QLC+ monitor, do you see the values flicker on it too ?

Or is it the physical lights only that flicker ?

The values are very fluid and do not flicker when I look at the monitor.

So..

midi from reaper -> QLC+ -> physical lights
=this flickers

manually adjust faders -> QLC+ -> physical lights
=this does not flicker


Here we could think that the issue is reaper->QLC+

but...

reaper -> QLC+ -> QLC+ monitor
=this does not flicker ?


Here I don't know where to look for the issue anymore

Well darn. Thanks for looking into it anyway. It's a very peculiar situation, and it happens on my laptop a lot, but less on my desktop. Weirdest thing.

Thanks anyway
