To replace his iPad for live performance, Colorado-based musician Toby Hendricks built a looper, complete with an impressive internal sound library, all running on a Raspberry Pi.
Toby’s build is a pretty mean piece of kit, as this video attests. Not only does it have a multitude of uses, but the final build is beautiful. Do make sure to watch to the end of the video for a wonderful demonstration of the kit.
Inside the Raspberry Pi looper
Alongside the Raspberry Pi and Behringer U-Control sound card, Toby used Pure Data, a multimedia visual programming language, and a Teensy 3.6 processor to complete the build. Together, these allow for playback of a plethora of sounds, which can either be internally stored, or externally introduced via audio connectors along the back.
Delay, reverb, distortion, and more are controlled by sliders along one side, while pre-installed effects are selected and played via some rather beautiful SparkFun buttons on the other. Loop buttons, volume controls, and a repurposed Nintendo DS screen complete the interface.
Code for the looper can be found on Toby’s GitHub here. Make sure to continue to follow him via YouTube and Instagram for updates on the build, including these fancy new buttons.
I got the music in me
If you want to get musical with a Raspberry Pi, but the thought of recreating Toby’s build is a little daunting, never fear! Our free GPIO Music Box resource will help get you started. And projects such as Mike Horne’s fabulous Raspberry Pi music box should help inspire you to take your build further.
