OMG... sorry TomHat...
I didn't saw your answer... I am so sorry!
Meanwhile these moving heads are sold as they did not use DMX, but an old MA-protocol (they were very old).
Anyway I am not following up Daslight4 to much anymore, since it is told to us, that this version won't be able to handle live adjusting of fade and waiting times, which is a "must have" (and a basic feature on hardware DMX mixer) when you run live concerts and you don't know, what songs will be played that evening. So it needs a flexibility in these settings, that DasLight4 can't provide at the moment.
So I am just using it for the lights outside the live stage, where light timings are not critical. But to give a positive feedback as well: DasLight4 never crashed on my hardware and I like the handling very much. So I maybe have to wait a couple of years for DasLight5
Kindest regards, Thomas
