in Standalone Mode, the XT2 works a little different.
Each cuelist is rendered as a stream of DMX frames and stored on the SD card. When you play a cueliste in standalone mode, it simply replays that stream. The XT2 has limited CPU capacity, which enabled us to implement a little on top (like max. 8 Cuelists are mixed HTP at the same time, Faders can be used, Mutual Exclude Groups, etc.). What does not work is addressing single Cues. So the Action “Goto Cue” for example will not work. Not sure what exactly you use in your show, but it could be that you use cues, Goto Cue action and MANAUAL cues, which are not supported standalone.
Triggers like Glass Touch buttons or the dry contacts of XT2 work.
In Device Manager, the T12 has to be drag ‘n dropped onto the XT2, so it will appear as a tree node under the XT2. Then its button actions will be exported.
During export, have a look at the export log. It states if you use Actions or Triggers which are not supported.
Hope that helps, Björn
