suppose you have 400 channels of LOR.
you import this file into xlights. How many channels are there?
answer is how many you defined in the SETUP tab. For example i have 24K channels or 48 universes defined in my SETUP tab.
if i import your file, it will say there have been 24K channels created. The first 400 are filled in, the rest are empty.
Now I go and create some models of megatrees, eaves, arches for rgb. I create effects and press save. Now the xseq file (that has 24K channels) has effects filled in. I then edit models, move things around. i press save. the xseq file will be updated with effects created in the new locations, any artifacts left from before are NOT erased.
if you have effects in places where you dont expect them, create a fresh sequence.
your original was called wizards.mp3, wizards.lms, wizards.xseq, wizards.xml.
create a new sequence , option 3 of open
click that you have a xml file
give it the sound file wizards.mp3
give it your sequence data file name, wizards.xml
save it on top of wizards.xseq
now you have your nutcracker effects populated. What about your LOR data?
just do a conversion
CONVERT
input: wizards.lms
output: xseq. It will default to wizards.xseq
click convert
your 400 channels will be loaded into the xseq and it will not touch the nutcracker effects.
any artifacts should now be gone
