Thanks for the update @AndyW. I'm interested into playing with this shield later on but with the vacation coming along soon it probably won't be before fall. One thing I would like to try at that point is to turn the core into some kind of an OSC to DMX bridge.
The idea would be to setup a series of OSC events that each trigger a specific pre-recorded DMX sequence when received by the core. I could use @kennethlimcp MicroSD shield to store the DMX streams and one of the OSC ports discussed here :
and here :
Anyway, I sure don't want to hijack this thread so I'll stop here while I can 
Once again thanks for this shield. I'll get back to this idea once the kids are back to school. In the meantime, enjoy the summer.
