emoctl - XMC-1 control script

#!/usr/bin/python

# Quick and dirty XMC-1 remote control.  Hard coded port and IP for now.
# Beerware / ian Butler / dualityk (emotiva lounge) / 9/2017

# Old XMC-1 firmware will wake up if the screen is off, but not do anything;
# you have to send a second command before it listens.  FW 4.1 is fixed.

# Set your preamp's IP here.  This is all you have to change.
