A few weeks ago I showed the system off to a stage manager who made the comment of ‘What if I don’t want to trigger the system via OSC?’ and I thought that this was a legitimate point. OSC is a very recent addition to lighting desks and sometimes their output capabilities are very limited. Likewise, analog sound desks very rarely have OSC capabilities, and although products like touchOSC exist they add another layer to an already busy operators job. This module is my solution to this problem.
As the name suggests, the DMX input module takes a DMX line out of the desk, and when triggered sends an OSC cue to the ROSA system’s server, triggering the system just like any other OSC capable software. This means that it can be used in conjunction with other OSC triggers or it can be used as the sole input for the system.
The way that it works operationally is that it listens on two DMX channels. The first channel acts as a safety, meaning that the ROSA system will stop all operation and will not acknowledge any new cues unless it is set to 75%. the second channel acts as a cue number. For example, if channel 2 is at a value between 1 and 10, it will fire cue 1, 11 to 20 is cue 2 etc. These intervals can be as small as 1% (giving a potential 100 cues) or as large as required.
Below is a video rundown of the module I created. My goal is to create one of these videos for all of the existing modules as well as any new modules I create.
As a side note this module also has a non-ROSA use as an OSC trigger. The OSC strings it fires can be completely customised such that you could trigger other show relevent programmes from any lighting desk which outputs DMX.
