Hi! When I was programming tonight, I noticed that the strips on the preview display were showing up in the wrong order. My tree is going to be 12 strips, 4m long with 10 ICS per metre (40 per strip). I had the direction of the channels and all that set up correctly, however on the display string 4 comes on instead of 1 and its a bit all over the shop. I then just created a matrix (40 high and 12 wide) for the 2d tree and low and behold the programming is fine and does as I expected. Is this a fault in the 2d tree settings in preview? I am very happy with LSP. It has a few bugs but once you know your way round its pretty user friendly.
