Ranjanpa--as Sean has noted many many times, exporting XL/NC into LOR is a painful way to do things.... I did what you are looking to do when I added RGB arches to my 2013 display and it worked well. I set effects for my 6-60 RGB arches in XL/NC, then exported the entire XL/NC xseq file into a dummy LOR LMS file. I then copied each row (each arch group containing all 60 RGBs--180 channels each arch...) from the dummy file and pasted each row into the target LMS file. I saved the target LMS file then used LOR to run everything. That worked really well, but I only had 1080 channels total. If you have lots more channels, LOR will get really slow.
