How to Add Multiple Fixtures with Same DMX Address

if you want them all to do the exactly same thing - I just make them all that same address.

I don't want them to all do the same thing.  They are focused on different areas of the stage and highlight different performers during different times of the performance.  In MyDMX on the patch screen, when I add a light, it adds the light to the patch (let's say DMX channel 1) and also add a "fixture" represented as a square at the bottom of the screen.  How do I get the second square at the bottom of the screen also on DMX channel 1 which would represent my two lights both plugged into the same dimmer pack?

Hi Jim, please watch my video on getting started programming on MyDMX 3, it should help explain that the program is fixture selection based.

Jingles,  

I watched you video and maybe I missed it but I didn't see where you can add two fixtures and assign the same DMX address.  I mainly want this so I can visually see the layout of my lights on my light bar as well as in the 3d viewer.

ah ok, sorry i misunderstood. 
in the program you cannot duplicate a fixture in the patch or in the 2D plot, but you can duplicate the fixture in the 3D. 
when you go into Edit mode on the 3D, in the objects section, expand fixtures, then the folder for the fixtures you want to duplicate and then right click the one hit copy, then right click on an empty space near it and hit paste. 
See pic attached. 

Thanks Jingles!

I know this is an old thread but I didn't want to create a new one.

I am working on a setup that uses 4 Gobo lights with a DMX 512 controller.  They have been using one light on address 1, which sometimes serves as a spotlight, while the other 3 are on the same  address 17.  They use scanner 1 when they want the spot, and scanners 1 and 2 together to control all 4 in conjunction.  The owner would like to mimic this configuration in MyDMX3.  I have set it up to respond properly to the sliders, but the software GUI only shows a single Gobo for that address.  Is there a way to do this?

Nixzero, you are essentially asking for the same thing, to be able to duplicate the same fixture in the patch but at the same address, which isn't possible.

Note, if you copy fixtures with same address in the viewer, you can position them as needed and it's a beautiful thing......until...you do anything in the patch window, then it will reset the fixtures to only one.     dang!  I had spend a lot of time positioning all the fixtures and then bam!

Hello, I'm new to DMX lighting (had always just had them lit or ran in sound mode).  I've been attempting to get used to the MyDMX 3.0 software and get my head wrapped around it.

I've got a Spider Head setup with several scenes that are linked together to run in a loop (as an attract mode for video game attraction) and it's triggered to start and stop via the I/O port.

My issue is that I want to add a second Spider Light and have it mirror the first one that I've set up.  I followed James's technique to copy and paste it using the 3D Visualizer and it looks all pretty in there but it doesn't seem that those settings have copied over to the MyDMX 3.0 software so I can push them to the box so we can run Standalone.  What step am I missing?

hi, sorry for the delay on this, but if you are using the same DMX starting address on both, then both will do the exact same thing as you already have programmed, there is no need to copy then paste fixtures with the same DMX starting address, my method is purely for visualization on the 3D, it will have no bearing or effects on the physical patching as its just a clone.... make sense? 

Yep that makes sense, but I do want to see them in the 3D visualizer so I know what the stage will look like when I set up a show.

So, then what is the exact issue you are facing? the copy ands paste in the 3D should work, and if its the same fixture at the same starting address, i don't see the issue, it should follow the same commands as the 1st.

That does make sense I guess.  If I have two fixtures and I have them both set up with the same ID then they'll both function in the same pattern.

What if I wanted one to mirror the other one?  I.E. they are on the ceiling about 8' apart and I want them to run the same sequence but in a (horizontal) mirrored fashion?

They are running in 17 channel mode, so the first fixture is set as ID 1 and the second would be set as ID 18 (if I'm understand this correctly).   All of my software sequence is set up to run for channels 1-17 but I want all of those scenes to mirror themselves to the second fixture.  That would mean that I'd be looking for all the settings for 2-17 to copy over exactly to 19-34 and for all the setting for 1 to copy over to 18 but in an inverted fashion (because that's the horizontal movement channel). 

Is there an automatic way to expand the existing show like that or is it hours of manual entry (better off to scrap the show and start over again)?

The copy and paste works, but as soon as I patch anything different, it resets the fixtures in 3D.  (Removed all the copy and pasted ones and their positions)

FEG: you can still use the duplicate address but just use the invert pan or tilt options that should be built into the fixtures menu.
Otherwise yes, you will have to reprogram your show.

SteveMichigan: We've heard of that being an issue when using duplicates, but it just hasn't been fixed yet in any subsequent updates in the 3D.... its in the hands of the developers. but we are aware of it and its on the buglist for sure!
