Open DMX is an unbuffered interface, which means it relies on the computer’s CPU to generate the DMX signal. In the meanwhile we were also able to investigate the issue with the Open DMX interface and were able to reproduce the flickering you encountered. Good to know things are running smooth for you with the Enttec DMX USB Pro! Still, there are many reasons why flickering could be happening, including things we are not yet aware of or problems that only appear using certain configurations, so it’s always precious to get these reports and try to get to the bottom of issues together. While we have not heard whether managed to make his Astera Titan Tubes work as expected, I would like to add I was recently able to control 26 Astera Titans using Beam with zero issues in an installation that ran non-stop for ~12-17 hours at a time :-). Using the Strobe device (in Live) with Strobe Rate set to something other than 0.DMX starting address mismatch: the starting address in the Beam patch is something else than what is set on the fixture or wrong address offset between multiple fixtures (if the fixture profile channel count doesn’t match the selected DMX mode).A fixture profile where the default DMX values for Strobe and Effect channels are other than 0 (according to your fixture’s manual these channels need to be set to 0 in order to be used in a continuous, non-strobing manner).A wrong fixture profile - here I mostly have in mind wrong channel order or using a fixture profile for the correct fixture, but for a different DMX mode than what the fixture is set to.That can be due to (I am mentioning some things that are maybe already obvious to you, but still mentioning them for others that might come across this post in the future): The most likely explanation for the behavior you are experiencing is that Beam is for some reason sending DMX values “other than what you would like” to the Strobe (ch5) or Effect (ch6) channels. How are you connecting your DMX interface to your computer? If it is a USB DMX interface, is it plugged directly into the USB port, or are you using a USB hub? If it’s a USB hub, are there any other devices plugged into it? If yes, is it an audio interface that is also active while using Ableton? If it is a laptop, is the computer running on battery or power adapter?.What DMX interface are you using to control it?.
