This controller flashes tri-colour LED strip lights for 50mS per note.Blue for G5 to D#6, red for E6 to B6 and green for C7 to G7. The controller is an ALSA MIDI device so MIDI software can output to the LEDs at the same time as a MIDI synth device like the Spielatron. The tri-colour 5V LED strips and Arduino Nano were purchased from Banggood.”
