I just downloaded and checked out xLights 0.2, I really like where this program is going, with its emphasis on interfacing with the hardware and doing it well.
I am currently running a Ledtriks with a Triks-C doing most of the work. Vixen has a launcher output plugin that is used to run the program (ltc.exe) that interfaces with the Triks-C. Based on a given intensity in the Vixen sequence, the launcher fires the specified program. Is there any way to do something like this in xLights or is a feature that will need to come in due time?
