This is my second instructable on using the Raspberry Pi for digital audio, check out my first instructable for how to set up and control custom audio effects on a Raspberry Pi. If you like them, please vote for me!!
If you like messing with audio effects or making digital music, you might have heard of MIDI. For the rest of you savages, MIDI (Musical Instrument Digital Interface) is a standard method for communicating musical information between two or more electronics. I first heard of MIDI in the early 90s as a kid, thinking “What is this awful music playing on geocities webpages?” Synthesized music has improved a lot since then, with various controllers, synths and MIDI interfaces available to dubstep and warble to your heart’s content.
Enter the PiMiDi: A MIDI interface built on a Raspberry Pi. There are a few commercial USB MIDI interfaces on the market that would work with the Raspberry Pi, but since the Pi has built in UART (a serial hardware platform used by MIDI), I decided to make my own MIDI interface. If you’re interested in learning how to make your own, grab your materials and let’s get started!
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
