MIDI-Lighting-Keyboard

I want to make MIDI input LED Lighting Keyboard

https://www.youtube.com/watch?v=wxcFKcL9LIE

Hardware.

Arduino Uno + NeoPix(WS2812) 128pcs

Hardware Connection.

PC USB --> Arduino Uno --> 470 Ohm --> Neopix

now Testing... Arduino MIDI <-> Serial Bridge

PATTERN1: LoopMIDI + HairLessMIDI (because,windows CANNOT open "31250bps" MIDI speed.)

PATTERN2: Change Arduino USB-MIDI (Use "Moco Lufa(atmega16u2)")

Software.

Loop MIDI (https://www.tobias-erichsen.de/software/loopmidi.html)

Hair LessMIDI (https://projectgus.github.io/hairless-midiserial/)

Moco Lufa https://github.com/kuwatay/mocolufa
Click "Raw" to Left Click and "save as a new file"
https://github.com/kuwatay/mocolufa/blob/master/HEX/dualMoco.hex

Flip (for atmega16u2 flash) https://www.microchip.com/developmenttools/ProductDetails/FLIP

Arduino library

FortySevenEffects/arduino_midi_library (https://github.com/FortySevenEffects)

adafruit/Adafruit_NeoPixel (https://github.com/adafruit/Adafruit_NeoPixel)

Fast LED https://github.com/FastLED/FastLED
Fast LED reference
https://github.com/FastLED/FastLED/wiki/Pixel-reference

Software Setting.

1. Loop MIDI (for Windows.)

   "+" to create new port.

2. Hairless MIDI<-> Serial Bridge

   setting at File -> Preferences -> "38400bps"

   "MIDI In" set "loopMIDI Port"

   "Serial Port " set "Arduino Uno (COM*)"

Program with Arduino IDE

if you Program Arduino, Loop midi "Serial <-> MIDI Bridge " turn OFF!!!

Arduino Uno -> USB-MIDI

Use "Moco Lufa".

If you Windows "Microchip FLIP"

If you Mac "dfu-programmer"
https://qiita.com/yasuraok/items/8ae995b7484e140b071f
https://sourceforge.net/projects/dfu-programmer/files/dfu-programmer/

1. USB Cable off Arduino Uno

2. ICSP 5-6 Short (atmega16u2 ,near USB connector)

3. USB Cable Set Arduino Uno

4. Flash "Flip" or "dfu-programmer" <dualMoco.hex> at Atmega16U2

5. ICSP 5-6 Open

6. USB Cable Off-Set

7. ICSP 4-6 Short to USB Cable Set (Arduino mode)

8. ICSP 4-6 Open to USB Cable Set (MIDI-USB mode)

Problem

1. timing Little delay?

2. After Lighting. "Note Off" and "Volocity 0" //That ch note LED OFF.

   and "ControlChange"

   120 is All sound Off //121 Reset All controller // 123 All Note Off : All LED OFF

   but Still Light LED there... Maybe, Serial or Handller Problem...
