The first thing you need to do after downloading xlights is to setup the show directory.
1) "File, Select Show Folder"
This could be as follows. Substitue my username for yours
LOR: C:\Users\smeighan\Documents\Light-O-Rama\Sequences
LSP: C:\Program Files (x86)\Minleon\LSP Sequencer
Vixen: C:\Vixen.2.1.1\Sequences
or you could just make a folder where things will be stored
C:\Vixen.2.1.1\Xmas2014
NOTE: Whatever show directory you pick, this is where you MUST put all your audio files. If there are no mp3 files, the file open option to create a sequence from music will be grayed out.
2) Next you need to add controllers to the SETUP tab.
You can add these controllers
USB DMX
USB Pixelnet
USB LOR
USB D-Light
USB Renard
USB OpenDMX
E1.31
3) Click save when you are done getting a pile of channels defined.
you are donw. FOr my 24 universes of E1.31, this whole setup process takes less than 30 seconds.
