I'm using Vixen 3.2.1 and have a series of WS2811 pixels in different strips (8 strips, 280 pixels in total in one string). I have the first strip plus the third and fourth strips with the red and blue ass about, the rest are fine. I thought it may be an element setup issue as the swap happens when the string gets to a new element but the first strip forms only half of one of the elements, the last strip forms the other half and has the correct colours. The DA_e131 test software shows the correct colours across the entire string. Any ideas?
