'''
Sniff packets from interface en0 using python module scapy (2.3.1)
and generate led color for bhoreal in usb midi mode depending on packet port number

Led are midi notes (0 to 63)
Color is a midi parameter (velocity) so 0 to 127.

To modify the network interface (wifi/ethernet), change it in the last code line.

Uses mido to send MIDI messages directly in python.
