 Forward incoming midi messages as OSC message (UDP) to micropython host to trigger hardware event. In example : noteon, noteoff lights on/off some leds connected to an ESP 8266.
 
 Remember to edit netconf.py for network/OSC configuration.
+In this early version you also need to edit in main.py :
+
+	- On your midikeyboard the left key midi notenumber : i.e leftnote = 36 
+	- motherip and motheroscport if you want some debug information.
+
 Connect the led strip data line to D5 (GPIO 14)
 
+How it works ?

 * Computer side : List and hook to all midi devices (real or virtual). OSC commands generated from incoming midi messages :
 	- /noteon midichannel, note, velocity
 	- /noteoff midichannel, note
