Build a MIDI visualizer with NeoPixel LEDs and the PropMaker Feather RP2040. A 3D printed grid display is inspired by the light billboard from the movie, Close Encounters of the Third Kind.

When connected with a MIDI keyboard and DAW (digital audio workstation), as you play, multi-colored LEDs light up the display with each MIDI note mapped to an LED NeoPixel.
The NeoPixel LED matrix is a 6x12 arrangement that features a grid of rectangular segments. A piece of acrylic is overlaid over the grid to diffuse the LEDs.
When a MIDI note is received, a corresponding segment is lit up in the grid. A total of 72 LEDs are mapped to MIDI notes C1-C6. Each row of NeoPixels is mapped to an octave, with a total of 6 available octaves.
