Q Light Controller+

Have a somewhat odd behavior with chasers.

Here is the rundown,

I created a candle flicker effect on 4 dimmer channels.

I created 9 scenes for the flicker effect on 4 channels/candles

I put them all in a chaser, set timings and selected loop.

Runs great, but of course I start to see patterns, so I select random.


In the Virtual console I have that chaser tied to a fader so I can dim, or dial in the correct brightness for the flicker effect. When it is on "loop" everything works correctly, the glitch occurs when the chaser is set to random. Say I have the VC fader set at 50%, the effect works correctly in dialing down the effect to 50% of my programed values, however about every 5-50seconds, the brightness of the chaser jumps to 100% for the fraction of time that scene is displayed. (in this case, about .10 sec)

Nothing is changing in the VC, however in the Simple Desk I see all the faders jumping with the lights. These random glitches only happen with I set the chaser to Random, running on a normal loop does not produce the glitch.

Hi, any chance you could share your show file and any custom fixtures so we can see what you are doing. Also what OS are you using and version of QLC+.

Thanks

The chaser in question is "2015 Flickers". The VC fader for it is in the nanokontroler box, 3rd fader called "Candles".

Running Ubuntu with Xubuntu Desktop installed. 64bit. 4.9.1 QLC.


Also, glitch does not happen in ping-pong mode, just appears to be random.


The p36 fixtures should be the only custom ones in there, but they are not involved with the glitch. If needed, I think I need a quick point where those are stored.

Also, just noticed other chases with the same glitch. On the VC, Control Knob 'Fire' for chaser Fire, also set at random in the chase settings, it will also randomly glitch back to full scene brightness while dimmed.


I ran both Flickers, and Fire together, both have separate timings, both glitches at at their own times (not at the same time).


(Yes, I know it's weird having all these flicker effects)

Hi,

Thanks for sharing the informations

I've found where the issue is located: when the random order causes the chaser to run the same function 2 times in a row, the second time the function is ran, its intensity is reset to the maximum value.

A fix has been pushed to GIT

Awesome, thank you!

I'm not quite savvy enough to build it myself, but I look forward to the next release.
