Many paths to get there... There were issues with reliability of the export to LMS in that past and for some users, Seilbeck, myself and a few others, actually stitch together multiple 25second LSP sequences into full length sequences as LSP cannot handle the data quantity of our sequencing technique.
In addition LightElf will batch convert your sequences from LSP to XLights, conductor, etc... If you need to convert 10 sequences from LSP to Xlights elf is by far the fastest way to do it. Which is what I had to do 3 years ago after LSP destroyed my lights on party...
