remember that iseq files have hard coded channel numbers.
if your LOR sequence had minitrees from channels 50 to 60
and it had arches from channels 1-30 then i would need to have those two sets of channels in my show.
You can offset the iseq as a group, so i could move the entire iseq file and have this
arches channels 11-40
minitrees 60-70
If you share a xml sequence file, then the channels dont matter. You match up models.
you would do things like
"Your minitrees from 50 to 60 will go to my minitrees channel 300-500"
"Your arches from 1-30 will go to my arches 600-660"
In other words, much easier and more flexible to share the xml sequence files from xLights instead of iseq files.
If you did hours of sequencing in LOR and are using the iseq overlays, then just understand the limits.
