  • Hi,

    I used DMXC3 on my last show with compelet 2 universe utilised for lights.

    1.There was some crash seen while editing, the timecode gets crashed when shifting from 1 timecode to another also timecode needle hangs as well when playing.

    2. When i use color wheel during the show, the software gets hang or we have to restart.

    Any solution please let me know!

  • I am facing issue when i use Timecode. The pointer on the timecode always hangs visually but the cues and audio track works good.

    Also on my last show i loaded 10 different tracks and used time code indivisually on them and triggered these cues with the LTC signal coming from another laptop on main stage running abeleton. When i switch timecodes one after one the DMXC3 crash on the 5th or the 6th timecode and then i have to reopen it again, i tried this thing and its doing the same always.

    Also during the show if i use color wheel sometimes the DMXC3 gets hang for 2 to 3 minutes and it gets back automaticaly.

    Ah ok. This is some sort of known bug which we currently can not handle. The problem is that DMXControl 3 is running out of memory. We have to load all the images of the soundfiles into the memory. And we tried to force the UI to throw them away if they are not in use anymore. However, we had no luck with that so they remain in the memory (is some sort of a known issue for the framework we use). We will be only able to address this issue when we have replaced enough window modules of DMXControl 3 to have one common framework basis (and not a mixture of three like currently). So unfortunately, this issue will continue to popup if you load multiple timecode shows in the timecode player.

    However, some users reported that if they keep the timecode player closed during the show, it will not load the files and thus will not crash DMXControl 3. So you can trigger it with commands (like you already do) and keep it closed and this should do the trick.

  • Ye i used the same trick as i didn't opened any of the timecode during the show and was only monitoring the cues of that timecode to make shure that it gets triggered by midi and it was working good but one of the timecode was not triggered so i have to use my midi controller to manually sync the lights.

    Is there any chance that these bugs are going to resolve soon?

    Changed the title of the thread from “DMXC3 crash/Hang” to “DMXC3 crash / hang when playing multible timecode shows”.

    We try our best but I think this will take some time. We have to replace at least three major window modules (Input Assignment, Stage View, Programmer) in order to kick out one of the three frameworks (and subsequently can switch to a 64bit version). So as you can see, those modules are larger ones and we will need some time to replace them. So unfortunately, there is no quick fix for that. If we would know one (for our some sort of special structure), we would try to implement that.

  • Hello. I just wanted to mention that I found the out of memory issue causing the crash when there are multiple timecode shows in the project and you switch between them. It will be fixed in our next release. Unfortunately there is no date yet for that release.
