Control GPIO pins over the Network with MIDI using MMKServer

  • by

The GPIO (General-Purpose Input/Output) pins of the Raspberry Pi are versatile ports for handling both incoming and outgoing digital signals. When used as output ports, GPIO pins can control lights, actuators, motors, relays and many other things.

One neat thing you can do with them is map them to MIDI “Notes” and play them as output devices. Using McLaren Labs software, you can share these over the network and “play” them from a remote computer. This article says how.

Here are the steps.

  1. Install midi2gpiod
  2. Install MMKServer
