Tyler Worman over at MAKE wrote up this great tutorial on building a three-switch effects looper for the BeagleBone Black.
Many artists will use looping stations to slowly build up an entire song in real-time as they play, recording one track at a time. There are plenty of great examples of this on YouTube. This project will show you how to use a BeagleBone Black, sound card, Python, and Pure Data to build an audio looping station for use with instruments. This looping station will allow you to build a loop, alter tempo, and adjust the loop as it plays. You’ll also lay the groundwork for building very complex synthesizers and effects pedals using the BeagleBone and Pure Data.
Each Tuesday is BeagleBone Black Day here Adafruit! What is the BeagleBone? The BeagleBones are a line of affordable single-board Linux computers (SBCs) created by Texas Instruments. New to the Bone? Grab one of our Adafruit BeagleBone Black Starter Packs and check out our extensive resources available on the Adafruit Learning System including a guide to setting up the Adafruit BeagleBone IO Python Library. We have a number of Bone accessories including add-on shields (called “capes”) and USB devices to help you do even more with your SBC. Need a nice display to go along with your Bone? Check out our fine selection of HDMI displays, we’ve tested all of them with the Beagle Bone Black!
