I’m doing an audiovisual performance this spring and need some help setting up the lightning part of my performance patch. I’m having a hard time trying to “split” control over fixtures so I can, for example, control the color of all my fixtures with a [swatch] through [jit.matrix] and let audio modulate the dimmer.
I’m using 4 fixtures, Fun Generation LED Pot 12x1w, in 6 channel (the only option in beam) mode. In the example patch below, I show how I’ve patched so far. I use [beam.join 5] as I hope to use a master color control [swatch into jit.matrix] with four independent dim controllers (and strobes as well but that is not an issue right now). But when I dry to dim the sliders it only dims the white channel (5) and only a little bit of the dimmer channel (1). The only “fix” I’ve found was by setting mix to -1, but it only seems to reverse the channel order, as the colors of [swatch] don’t match the dmx output.
The dmx channels on the fixture is set up as following 1-dim 2-red 3-green 4-blue 5-white 6-strobe. Also, when I control click the inlet of the tag (both tags are assigned to the same fixture!) it doesn’t show the white channel, only RGBS.
And thanks for a great product, I just need to learn how to use it properly…
Ok, so I have tried some different approaches this morning and found a, kind of, fix.
See the .gif attached below. With this setup I would be able to do basically what I want. But I still have some questions/possible request if it’s not possible.
Below you can see I only prepend @dim for each of the fixtures individual tags. But changing the @dim value changes every channel tagged, dimming all channels and not just CH.1 DIM. Is there any possible way to set the rgb, and change CH.1 DIM without it affecting the RBGWW parameters?
Hey! While I can’t fully decode your gif, I tried loading the Fun Generation LED Pot 12x1w fixture and can indeed see that both the dim and the color channels are being scaled instead of just the dim channel. I’ll have to do a bit of investigation to see if this is a bug or not.
As a workaround, you can make a custom fixture profile. Attached is a profile you could try. I changed the profile’s colorspace from rgbwi (RGBW + dim) to rgbw, and added a separate modulation name for the dimmer channel. Now, using [swatch] will set the colors and ignore the dim channel, and the custom_dim message allows you to control the first channel separately.
Hopefully this unblocks you while we do some investigation!
Thanks, hidde. I made the gif in a rush as I had a flight to catch and wanted to show the patch behavior. I will try out the custom fixture you attached as soon as I get home from vacation, and I will let you know how it goes.
Grateful for Beam, was a breeze to setup an interactive installation last week (https://youtube.com/shorts/k1cFpXEfvig?si=KMIwcXY923IHn1NH) where local kids joined a workshop and experimented with video manipulation to change the pixel lights thanks to beam.matrix. Really hope (and believe!) I can find a lot of usage from beam.
