Bind MIDI inputs to LED lights using a Raspberry Pi #piday #raspberrypi @Raspberry_Pi #Music

Redditor Aaron Chambers shared this midi project. Here is more from Raspberry Pi:

Controlling lights with MIDI commands

Tentatively titled Py-Lights, Aaron’s project allows users to assign light patterns to MIDI actions, creating a rather lovely blinky light display.

For his example, Aaron connected a MIDI keyboard to a strip of RGB LEDs via a Raspberry Pi that ran his custom Python code.

Aaron explains on Reddit:

The program I made lets me bind “actions” (strobe white, flash blue, disable all colors, etc.) to any input and any input type (hold, knob, trigger, etc.). And each action type has a set of parameters that I bind to the input. For example, I have a knob that changes a strobe’s intensity, and another knob that changes its speed.

The program updates each action, pulls its resulting color, and adds them together, then sends that to the LEDs. I’m using rtmidi for reading the midi device and pigpio for handling the LED output

.
