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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
