I did the exercise -
I have three LOR controllers - LOR 1 - mapped 1 to 16 in Xlights, LOR 2 - mapped 17 to 32 in Xlights and LOR 3 mapped 33 to 48 in xlights.
Upon conversion I am not able to see channels 17 to 48 in verbose channel mapping, however the odd thing is that when i play the sequence in Layout tab of XL, the minitree do light us but not in perfect sync.
Dont know how to debug. Help appreciated.
