Q Light Controller+

My fixtures don't seem to like the Master Timer frequency set in the program. A queue seems to build up of DMX instructions causing the scanners to move very slowly from one step to the next. In the original QLC I was able to adjust the "MasterTimer" variable in the source code and re-build...

/** The timer tick frequency in Hertz */
const uint MasterTimer::s_frequency = 25;

...I found that 25Hz seemed to work OK with my fixtures. Obviously the new QLC+ is back to the default (which might be around 50Hz). Is there a way to change this without re-building the program?

Massimo did give me instructions to change the output frequency of the USB DMX interface, by editing the "net.sf.Q Light Controller Plus.plist" file (I'm using a Mac) and adding...

<key>enttecdmxusbopen/frequency</key>
<string>25</string>

...to the bottom, but this doesn't seem to do anything though, the fixtures are still responding slowly. Here is a screen shot of my output configuration...

...it looks as though I have an "FT232R" interface made by FTDI. Would the above setting be correct for this device, as it's not an Entec?

Failing this I guess I'll have to re-build QLC+ too, with the new Master Timer setting.

Many thanks,
Chris

I was searching the topics because i also have some flickering at 1 RGB controller. I can't find the file net.sf.Q Light Controller Plus.plist in the library?

Hi,

You can change QLC MasterTimer trough Windows Registry.
Simply - make a file: "QLC-tune.reg" containing:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\qlcplus\Q Light Controller Plus\enttecdmxusbopen]
"frequency"=dword:00000023
[HKEY_CURRENT_USER\Software\qlcplus\Q Light Controller Plus\mastertimer]
"frequency"=dword:000000c8

and put it into registry.

Value "dword:000000c8" means 200Hz, and it helped for me.
If you want 25Hz change it to "dword:00000019"

Hope this help
