My setup, I currently have about 96 channels AC, and a 600 pixel tree, all LOR. I use superstar and visualizer. The first string on the pixel tree is 9 o'clock. I'm looking at alternatives for this year. I created some effects in xlights/nutcracker for testing. I use the export function to LOR. I then just copy and paste from this file to my working file. I then play in my visualizer. The effect I mentioned in the original post is oriented at the 3 o'clock position. I'm trying to rotate 90 degress clockwise. I changed the first string setting to 3,6,9, no changes were noticed.
