Closed JonnyTech closed 9 months ago

JonnyTech commented 9 months ago

Describe the bug Single channel in QLC operates on three physical fixtures

To Reproduce Steps to reproduce the behavior:

  1. Connect a WS2811 LED strip
  2. Add fixture Generic RGB
  3. Go to Simple Desk tab 4a. Slider 1 operates red pixels on first three LEDs 4b. Slider 2 operates green pixels on same three LEDs 4c. Slider 3 operates blue pixels on sane three LEDs

Expected behavior Each lider should only operate on a single LED

Bro this is how LED strip like this works.

You bought the cheap version which has 3 segment groupings.

Talk to your supplier if this is not expected

Thank you, I was completely unaware of groupings. How would I know what to look for? There is no documentation showing that unless I do not understand the terminology.

Thank you, I was completely unaware of groupings. How would I know what to look for? There is no documentation showing that unless I do not understand the terminology.

Your supplier will tell you if the strip is grouped like this, it's not really up to QLC+

For example, this strip is grouped: https://www.enttec.com.au/product/led-pixel-strip/black-led-pixel-strip/

While this strip allows individual control of the LEDs: https://www.enttec.com.au/product/led-pixel-strip/8px60-12-b2-5m-black-12v-single-led-control-pixel-strip/

Most of the time, the dead giveaway is the copper attachment points.

Notice that on your strip, the copper pads come every 3 LEDs where as on most individual controlled LED strips, the copper pads will be present after each LED.

Hope this helps. If you have any further questions please make a forum thread.
