MIDI_MSC_SysEx.lua

--[[
Made by: Ted Charles Brown
Version 1.0.1

HOW TO USE:
 - Add a MIDI module to Control.
 - Add a "NewModule" to Control.
 - Right click in the "newModule" and select "add action" (or add a new action to the MIDI module to get around node counts).
 - Name the module "mscIn(data)" - data is the variable name and must be included.
 - Copy and paste this code into the code section of that new action.
 - In the MIDI module, under Receive, SysEx, drag the output to the input of the new action.
 - Edit the deviceID, cueList, and timelineName variables to match your setup.

NOTES:
 - Currently does not support pause, resume, fader, or macro commands.
