midiOSCesp

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
- /rawcc midichannel, CCnumber, CCvalue
- /clock
- /start
- /stop
Micropython/ESP side :
- interpret /noteon and /noteoff and switch one led in a led strip. Changing or adding functions to clock or other midi msg is easy, look lserver.py.

- Micropython firmware (select v1.13 with the right RAM amount): https://micropython.org/download/esp8266/
- Flash firmware, upload python files, run files,... thonny IDE : https://thonny.org/

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
