-Avolites Titan at the moment (Titan v15, 2022) sends sACN only as Multicast (automatically falling back to Broadcast if bo IGMP capable switch is present). While it has been requested to implement sACN unicast into Titan a solution is required to circumvent this for the time being.

 ... and along comes MIDIMonster. Available at https://midimonster.net this is something like the Swiss Army Knife for lighting protocols. It is a lightweight console application, available for Windows, Linux and OSX, where you simply write a configuration as a text file and then start the program. This comes at the extra benefit that you don't need drivers, nothing being installed, and this can even be run from a USB thumbdrive.
+If you download MIDIMonster from the above link, start it, and get this message
+''Failed to load plugin backends\lua.dll, check that all supporting libraries are present...''
+then you find [[https://github.com/cbdevnet/midimonster/issues/71|the solution here]], download [[https://sourceforge.net/projects/luabinaries/files/5.3.5/Windows%20Libraries/Dynamic/lua-5.3.5_Win64_dllw6_lib.zip/download|LUA binaries here]], unzip it, and copy the file ''lua53.dll'' into MIDIMonster's main folder.
+In order to run it you simply doubleclick ''midimonster.exe'' in which case it loads its settings from the file ''monster.cfg''. Subsequently you can either edit this directly with a text editor, or you write your own file with a different name and drop it onto midimonster.exe in order to start it with your configuration.

 All you need to do is adjust this to your needs (in and out universes, target network addresses, maybe more mappings etc.), save this as monster.cfg (or drop this on midimonster.exe, or call it like this: ''midimonster <path/to/configfile.cfg>'' (personally I prefer saving this as monster.cfg as I can simply doubleclick midimonster.exe).

   * midimonster takes very low processing power (at least in my tests with 4 universes converted)
-  * at least in my tests it was not possible to make this work with MIDIMonster directly on the console: it does run but doesn't output as required - the nodes see the universes but there is no data. I believe it is not possible to have two applications on the same machine which both attempt to send to the same port, and one also listens to the other.

+===== Trivia =====
+==== Picture: my test drive ====
+Yes, I really did try this with some computers (and Wireshark and sACN View - and the network switch is in the middle...)
+{{:tricks:sacn_testing.png?600|}}
+==== Video: another test, on a D9 ====
+And yes, I also tried running this directly on a console (and made one of those shaky videos with my mobile phone):
+{{youtube>35oClm_2i9Y?medium}}
+==== Wireshark screenshots ====
+This is an example of how the sACN network traffic looks in wireshark:
+{{:tricks:wireshark.png?600|}}
+Network addresses in this example (port 5568 is sACN):
+.0.0.1 - Titan PC Suite
+.0.0.10 - MIDIMonster
+.0.0.50 - the 'client' to the left (sACN View)
+.0.0.100 - the 'client' to the right (sACN View)
+.255.0.1, 239.255.0.2, 239.255.0.3, 239.255.0.4 are the automatically generated multicast addresses.
+  Packets from 2.0.0.1 to 239.255.0.1/2/3/4 are the multicast sACN sent from Titan.
+  Packets from 2.0.0.10 to 2.0.0.100 or 2.0.0.50 are the unicast sACN from MIDIMonster to the 'clients'.''
+This is an example of how the mixed Art-Nt/sACN network traffic looks like in wireshark:
+{{:tricks:wireshark_artnet.png?600|}}
+Network addresses in this example (port 5568 is sACN, port 4809 is Art-Net):
+.0.0.1 - Titan PC Suite and MIDIMonster
+.0.0.10 - the 'client' in the middle (sACN View)
+.0.0.50 - the 'client' to the left (sACN View) (no packets to this screnshot)
+.0.0.100 - the 'client' to the right (sACN View) (no packets to this screnshot)
+  Packets from 2.0.0.1 to 255.255.255.255 are the broadcast Art-Net sent from Titan.
+  Packets from 2.0.0.1 to (3.g.) 2.0.0.10 or 2.0.0.50 are the unicast sACN from MIDIMonster to the 'clients'.''
+Btw. 224.0.0.180 is another special auto-generated address which is used by CITP...
+==== Another idea: Raspberry Pi ====
+And very finally: [[https://midimonster.net/download.html|MIDIMonster]] is available for Windows, for OSX, and for Linux. Of course the next idea would be to run this on a Raspberry Pi. But this is probably something for someone else to do. Please let me know if you want to go down this route :-) .
