have not finalized all that yet but I do have the basics working. For example I should be able to time a DMX flame effect to match a firework effect on the same beat of music. You can then trigger DMX effects at the exact time you need to match your fireworks show.īoth the cobra script and the DMX script are started using the 18r2.
That signal is interpreted as a clock in the software running at the exact same time as the script in your Cobra. The converter then feeds to my compu show SDE DMX software on my laptop. When you do this you have the audiobox sending one RCA to your sound system and the other to a LTC to midi time code converter. You then use Audacity to get one channel of the audiofile with that timecode and the other with your regular audio which should be converted to mono from stereo first.
The audiobox can play a smpte time code LTC audio file on one channel. This allows just pressing the 18r2 button to start everything and both the fireworks and all the other equipment should stay in synch. The solution involves using the audiobox to send a timecode signal to the DMX hardware / software so they "triggered" at the same time. Plus with very precise timing like what is needed for a flame effect for example its really difficult to get timing right with that method.
Prior I had to basically press both start buttons at the same time and keep my fingers crossed they were aligned. The problem I have had is synching both these sets of software / hardware so they are both running on the same "time clock". You can program these with very precise timing for effects in a similar way you program cues in your script for firing on beats of music. use to control from either a computer running DMX software or a hardware control panel. Cobra has had DMX integration in the works for a while but based on some feedback from Scott and knowing the complexity of programming for DMX moving head fixtures for example I have been working on a solution instead of waiting for something that likely would not work for my hardware.įor those not familiar, DMX is the language nearly all special effects lighting, flames, lasers, etc.
