Hi Gang,

Using Windows 10 with QLC 4.12.5 and the Lixada USB DMX controller.

Having real issues starting up the lights. If I switch on the fixtures and then switch on the software/virtual console nothing works. No DMX signal is detected, the fixtures go nuts. DMX line is terminated on the last fixture.

If I shut everything down, start the software, start the virtual console, then start each light in the chain in sequence, in order, it works as expected.

This has happened twice at gigs now. The first time the lights just ran in STL mode all night. The 2nd time we had time to do some fault finding and managed to get them working properly for the gig.

Having to do a sequential startup in itself isn't a bad workaround as we don't have that many fixtures, but it's more time consuming than just switching on.

Has anyone come across this behaviour before?

Hi, 4.12.5 had a severe issue with Lixada devices.
That's why I released 4.12.6. Please try that.
