yamaha_MRX7D.py

#!/usr/bin/python3

#this is a basic control for yamaha MRX7D
#please see Yamaha white paper for specific information, this is only a basic code example for correct syntax
#you must first create under 'tools/remote control setup list' individual ID numbers for items you want to control
#the number immediately following "Index" below is the ID number of the item controlled, in this example it is a mute switch
#The complete manual can be found at:
