QLC program crash on run

[Centauri]

Can someone have a look at the attached show file & tell me why it crashes when try to run? It only does it when the loopback is applied to the "FlashDetect" knob. Worked fine with a smaller demo, but not with the full show programmed. Thanks in anticipation.

From a first glance I guess the problem is that you patched both input and output of loopback 1 to Universe 4. Try patching the input to another universe.

Anyway, some fixtures are still missing for this workspace file:

Code: Select all

No fixture definition found for Show Technology EA-8090 STRIP
No fixture definition found for Generic 36x1W R+G+B

Loopback doesn't seem to be real well documented, and the settings were based on other examples. A small demo I set up first with the same loopback settings worked fine.
Attached are the two missing files.

Ok, eventually found the issue by examining the qxw file as xml with Google Chrome.
Each of the universe entries had the line "<Feedback Line="0"/> which as far as I can gather assigned loopback1 to the feedback of all universes, although nothing appeared in the Inputs/Outputs tab of QLC+. Didn't affect running until I actually wanted to use the loopback plugin. Assigning then unassigning a loopback to each universe feedback deleted the entries from the qxw file & stopped the crashing. Have no idea how the offending entries got there, unless it had something to do with creating many of the scenes using the "Dump DMX values to a function".
Now I can get on with finishing the programming.

Or could have searched the forums and found this: viewtopic.php?f=32&t=11761
I really need to release a patched version cause this is getting reported too many times.
