Light show problems

Here is what im running: (will attach video of issues)

2 chauvet 260X
2 Shehds Beam 38 ch
6 Shehds Par 8x12 RGBWA+UV 10 ch

Note: when I was running the 260x alone it was working beautifully
I actually wrote some great material with 260x, generic par can (I programmed profile) and Beams on 9 ch. (I programmed profile) all working great.
It’s as if everything is “stepping on each others DMX toes “ even tho they are not on same dmx channels. it feels like universally there is conflict. For example my lights are set to go auto mode upon loosing dmx signal. Well, when the beams are on the movers freeze. Then turn the beams off and mover start to function. Make sense?
When I combined this new setup. It all went to crap. please help !! Lol

Problems:

-260xs not working at all (previous to adding the pars it was working beautifully)

  • Only one bar working and not properly. The red knobs makes green , blue knobs makes white, green knobs makes blue. (I could live with this glitch. But they are not functional at all with midi notes)
  • Pars do not function with midi notes. But everything else seems to be working fine. All the colors are correct and stuff. However the only way I can get it working is by rolling up a selected color and applying the intensity knob. Midi notes no triggering colors.

And yes … ya boy spent all his money on a recording studio and light show and therefore he has a futon in his living room :joy:

What a cool setup! Especially the futon area.

Could you please share your fixture patch and Live Set (can also be via email at firstcontact@showsync.com)? Also, what DMX interface are you using?

Hi Luka

I’m using entecc usb pro.(when I use the lights individually it works fine- except for the shehds beams. They don’t work on the new 48 ch patch. But when lights are combined it all goes wonky. I think I have 14 lights total) I emailed you the fixture patch and more details of issues. I also got a dmx terminator. I can use that on the last fixture to hopefully clear up some of the glitchy stuff. From my understanding when combining more lights together it’s encouraged to use a terminator. Something about the signal kinda “reverberates” if you will. Will report back on this later today.

MOSTLY RESOLVED

I figured out what most of the problems were.
I had channels stacked on top of each other not knowing. also the terminator really helped clean up the signal so there isnt the weird stuff happening.

Only problems left:

  1. the white function of Shehds RGBWA+UV isnt working. everything else is working fine.
  2. the Blinder isnt working on the nexys flux.
  3. Still having to force quit abelton when using Beam.

ALMOST THERE FELLAS> so close to having everything functioning properly.

Hi Caleb,

Nice you’ve sorted out most of the issues!

  1. the white function of Shehds RGBWA+UV isnt working. everything else is working fine.

I tested the patch you shared via e-mail in Capture and the white channel of the Shehds LED Par 18x18W seems to respond correctly when setting the color to white on a Beam instrument:

  • Could you double-check that the fixtures are set to the 10-channel mode (on the fixtures themselves) and the correct DMX addresses?
  • Can you confirm that the exact fixture model you have is indeed Shehds LED Beam Par 18x18W RGBWA+UV? There are some similarly named models from Shehds that have different DMX channel configurations.
  1. the Blinder isnt working on the nexys flux.

I think this is probably due to the way fixture profile I shared with you is made. The fixture manual lists color channels in 8-ch as simply Red/Green/Blue/Warm White…

…so I made a profile that will generate RGBW channel data for a chosen RGB color in Beam. However, looking at the product website and testing this in Capture, I now understand that Warm White and RGB are actually two separate sections, basically 2 fixtures in 1. The profile I originally made will only activate the Warm White/blinder section when you select a white-like color, but you won’t be able to address those sections individually.

Here is a revised fixture profile that takes this into account:

Blizzard Nexys Flux - 8ch.sbf (319 Bytes)
Blizzard Nexys Flux - 8ch (main).sbf (833 Bytes)

Copy these fixture profile files into your Fixture Profiles/User, overwriting the previous profile, and restart Beam.

In your fixture patch reselect the fixture profile once again:

If you now double-click on the fixture, you should now see the separate fixture sections:

You can simply use a single tag to control them all at once, or to address the sections individually, assign a separate tag to each of them and use 3 separate Instruments in Live, one for each tag:



  1. Still having to force quit abelton when using Beam.

Please try the build I shared to see if that resolves it & let’s continue the conversation about this via e-mail.

Hi Luka,

i think i may have figured out the problem with the shehds par18x18 RGBWA+UV. It is in fact that exact name and model. however on your profile in abelton it says waterproof. I have also since learned that to acheive white, i can blend 1/4 amount of RGB knobs and the result is white. I have confirmed that the DMX channels are correct and all the par fixtures are in fact in 10 channel mode Attached is the link to the exact fixture i purchased.
