Turning on individual beam in Shehds Beam 8x12

Beam for Live
1

Hi, I’m new to the whole lighting thing.

I was able to connect my Shehds LED Beam 8x12 RGBW to Beam 2.0 and abletone live 12. I’m using Enttec USB Pro to connect to my PC which is in windows.

I managed to turn on the beam and do some tilt control using generic instrument in Ableton using Beam plugin, but I can’t seem to figure out how to control individual lights in my beam. For example, I want to turn on left 3 beams out of 8 beams that is part of the Shehds LED Beam 8x12 RGBW.

Something that looks like [000XXXXX].

Any idea how to achieve this using the plug in? I can only turn on and off the whole beam. (selecting program in the paramter option seems to be triggering a preset program that involves controling the individual lights, but I do want full control instead of a preset).

Hi @sungjin0627, welcome!

As a reference for anyone else coming across this thread, fixtures like Shehds LED Beam 8x12 RGBW are basically many sub-fixtures within a fixture:

You can address individual cells of such a fixture in the same ways you can address individual fixtures within a Beam tag group:

I made a video that demonstrates this:

You can also use the Spread parameter of Beam’s LFO effect device to spread the effect across the cells.

Thanks Luka for the video.
I’m still having some trouble replicating the view you;ve shown in the video.

  1. How do I open the visualizer you use and set it up to mimic the beam bar?
  2. I am currently testing with the actual beam bar and few things to be off. The lights are green even when I have the color selected as red. Moving the shutterstrobe value only seem to change the dim of the red color. Also, when I try to adjust the dim params in Bar Cell device after adding all 8, only first one works by controlling the entire beam.

With first dim param set to 1.0 All lights are on green. In the demo video it shows red… so I’m confused. Also I was expecting only the first beam to be lit, but all lights are on.

With the second param set to 1, all lights are off. I was expecting only the second light to turn on, but nothing happens. Same for all other parameters.

I don’t know if I have something mixed up, but can you help me trouble shoot this?

Hi @sungjin0627,

  1. How do I open the visualizer you use and set it up to mimic the beam bar?

In the video I used the Capture visualizer, which you can get here.
Here is a short video that demonstrates how to set a fixture patch in Beam & Capture from scratch: https://www.youtube.com/watch?v=2MEBXl675qY

  1. I am currently testing with the actual beam bar and few things to be off.

The values in the DMX Monitor on both of your screenshots are looking correct and match the DMX channel layout of this fixture in 38-channel mode:

  • screenshot 1: channels 5 (Total dimming) and 7 (BAR1 R dimming) are active
  • screenshot 2: channels 5 (Total dimming) and 11 (BAR2 R dimming) are active

Both corresponds to what you are trying to achieve.

The fact that your fixture isn’t responding as expected most likely means one of the following:

  1. You haven’t set the fixture to the 38-channel mode - this is something you need to do on the unit itself.
  2. You haven’t set the fixture to the correct DMX address - this is something you need to do on the unit itself and needs to match the address in Beam’s Fixture Patch.
  3. You have another model/revision of the fixture that has a different DMX channel layout and needs a different fixture profile - please check the unit’s manual.
