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. 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) Connect the led strip data line to D5 (GPIO 14)
How it works ?

* midi learning software :
- This has been tested with Synthesia.
- Synthesia/Neothesia hook to midi OUT ports to send light guidance and obviously midiOSCesp listen to INcoming events. So you need to create a virtual midi port will forward event sent to its OUT port and to its IN port. https://help.ableton.com/hc/en-us/articles/209774225-How-to-setup-a-virtual-MIDI-bus
